Cement- particle board(DSP) is a material that is actively used in construction and repair work. Such plates are in demand in a huge number of areas. But even these fundamental designs are presented in great variety on construction market. Before choosing a specific product, you need to familiarize yourself in advance with the features of these structures and the areas of their use.

Production Features

Cement particle board is manufactured using special technologies. The process of creating a DSP includes the following steps:

• The solution is based on water, which is poured into a special mixing container. Aluminum, salts and liquid glass are also added to the container;
• for mineralization to take place, shavings elements are added to the mixture;
• on next stage cement is added;
• to obtain a DSP block, the solution is poured into a special mold;

• a certain thickness is given to the substance using a press;
• after pressing, the product undergoes heat treatment, during which the characteristics of the raw material components are taken into account;
• In order for the substance to harden, it is placed in special chambers. There, at a temperature of 80 C, the components are fixed;
• After hardening, the canvas is cut into sheets. Their sizes are determined by GOST.

Products are manufactured only in special factories, where strict control over the implementation of each stage is carried out. It is impossible to independently produce a high-quality DSP panel.

Characteristics

Cement-bonded products have a number of fixed technical characteristics that explain many of their properties:

• a quarter of the composition is made of wood chips, a little more than 8% is water, the main component is Portland cement and additional impurities account for 2 and a half percent;
• material thickness varies from 8 to 12 mm;
• The width of the slab is 120 or 125 cm;
• length – from 2.6 to 3.2 m. To order, you can choose a model up to 3.6 m long;
• the weight of one square meter of DSP, having a thickness of 8 mm, reaches 10 kg.

The material has a high density, which reaches 1300 kg/m3. During the process of moisture absorption, the density can increase by 2 percent. The limit of water absorption capacity usually does not exceed 16%.

The roughness of a CBPB board is the relief of each sheet. It depends on the grinding characteristics. Unsanded boards have a reading of 320 microns, while material that has been sanded has a reading of 80 microns.

The sheets have a fire resistance class of G1, which means that the material has low flammability. The thermal conductivity index is 0.26 W.

All of the listed characteristics allow you to select the required number and parameters of the building material.

There are also different kinds materials for slabs and cast products from CBPB:

• Xylolite– high-strength material with good thermal insulation. Such slabs are often used for flooring. Products are presented in a wide range of colors.
• Fibrolite is a raw material consisting of long fibers. He has high thermal insulation properties and soft texture. Biological factors do not have a strong impact on this type of DSP.
• Fine-chip materials include wood concrete, which is used in various fields.

Advantages and disadvantages

Like any building material, DSP has a number of advantages and disadvantages. The advantages of such plates include:

• The material is very resistant to moisture and temperature changes. The slabs can withstand up to 50 frost cycles. This characteristic significantly affects the service life of the slabs.
• The raw materials used to create such partitions are absolutely safe for human health. DSP does not release harmful toxins and does not cause allergic reactions.
• Cement bonded particle board is perfect for various transformations. With it you can use any finishing methods and change the surface of the product at your own request.
• A wide range of. In modern construction stores you can find a wide variety of products.
• The affordable price is an important advantage. Since the material is often used when building a home from scratch, purchasing large quantities of material will not negatively impact your budget.

• Cement-bonded products are easy to use. On such a surface it is convenient to carry out various renovation work using a drill, hammer drill or knife.
• The fixed size of the products significantly simplifies the installation process.
• The material is resistant to rotting processes.
• When a cement-bonded particle board is used to screed floors, it contributes to significant cost savings compared, for example, with self-leveling compounds or a cement-sand leveling option.

To negative properties of DSP can be attributed:

• Products can reach a large mass, which significantly complicates their use in high rooms. The high weight is due to the high density of the material.
• The material is not plastic. If you try to bend such a slab, you can break it. Risk of breakage during construction work explains the need to purchase material in reserve.

Based on the presented data, it is clear that DSP has significantly more advantages than disadvantages. The disadvantages of such products are easily compensated by their advantages.

Scope of application

Cement particle boards are used in various construction and finishing fields. The most common applications are:

• External . It implies the suitability of slabs for finishing the façade of residential premises and the use of slabs as a basis for fencing. It is also possible that work to implement permanent formwork. DSP sheets can be used both in private and industrial applications. These slabs are used to construct both protective structures for garden beds in private homes and parts for industrial enterprises.

• Cement particle board is indispensable in the construction of a frame house. In this case, it acts as an excellent insulation. The products are used to create heated floors. They are also often used for walls, subsequently creating interesting decor on the slabs.
• The material's resistance to moisture allows it to be used as ceiling covering in saunas and other types of premises where the humidity level is high.

• Often such sheets are used to create partitions in rooms. In order for the slabs to serve longer as a separator, they are coated with a special paint that performs a protective function.
• The best types of cement particle boards are used to create furniture.
• The material is used to create window sills. It becomes a more affordable alternative to wooden structures, and at the same time lasts no less long.
• It is permissible to make a special base for roofing in private houses from dense slabs.

• A very common area of ​​application for slabs is restoration. The material is often used to give old buildings a better look. In addition, due to their relatively low price, the products are quite suitable for large-scale work.
• Thin slabs are often used to decorate such attributes of private homes as fireplaces and chimneys.
• Cement particle boards are sometimes used as an alternative to cement when screeding floors.

DSPs are suitable for various types of work. The following processing options for cement-bonded particle board products can be carried out:

• cutting to required sizes;
• creating holes in slabs using a drill;
• milling work;
• increasing strength at joints using end grinding;

These capabilities characterize the DSP material as an excellent base for any coating and as a source for the embodiment of creative ideas.

Manufacturers

There are a number of manufacturers of chipboard products that are very popular in the construction market and have earned positive customer reviews.

Leningrad company "TSSP-Svir" provides light gray products with a calibrated surface. Also among the company's assortment there are polished models. The production is based on European standards and high-quality equipment from Germany.

Bashkir enterprise "ZSK" is also distinguished by the production of high quality slabs in accordance with GOST. Main feature products is their increased resistance to temperature fluctuations and the influence of weather conditions.

Kostroma company "MIT" characterized by special geometric characteristics of the product and strict adherence to all quality standards.

Tambov company "Tamak" produces high quality slabs. The company approaches its business very carefully, so it is difficult to find even the slightest defect among their products.

Omsk company "Stropan" is engaged in the production of elastic cement bonded particle boards of various thicknesses. The company is also distinguished by the creation of sheets with increased sound and thermal insulation.

Knowing the list of leading companies, you can easily choose slabs that you will not be disappointed with later.

Depending on how exactly you decide to use DSP for your home, you should listen to various recommendations for correct installation these slabs.

The most common option is to insulate walls or floors using cement bonded particle boards. To carry out this procedure, it is necessary to prepare the surface of the walls in advance by providing it with metal and wood lathing. It is necessary to have special cells having a fixed size of 500*500 mm.

During installation, leave 1 centimeter space between the plates. It is covered with a special cover, for which you can use finished products from the same material or create them yourself from residual raw materials.

To secure the canvas, you must use nails, screws and self-tapping screws. You can attach alternative ways– using mastic or a special adhesive solution.

To insulate a frame structure, slabs must be installed on the outside and inside of the walls simultaneously. If you want to insulate a utility room, then it is permissible to leave small space between the base of the wall and the DSP sheet.

In private homes, many people install cement bonded particle boards on wooden floors to make them warmer. To correctly carry out this process, you must follow a special algorithm:

• To avoid creaking floors in the future, the base is adjusted and secured with self-tapping screws. When adjusting the base coating, it is imperative to remove rotten boards and replace them with new ones. If there are cracks or cracks of an insignificant nature in the surface, they must be treated with putty.
• Room measurements are taken taking into account the location long side cloths across the boards.
• It is necessary to design on paper a diagram for laying CBPB.
• Using a grinder, you need to cut the sheets to the required parameters, if necessary.
• The slabs are installed in the direction from corner to corner. In this case, it is best to fix the products using zinc screws.
• The seams between laid sheets should be primed. Only after completion of all stages can external finishing be carried out flooring.

A special process is the use of DSP for floor screed. To correctly carry out the dry screed procedure, it is necessary to lay the sheets on a special filler with granules and metal profiles made of plasterboard or wooden blocks. Self-tapping screws for fastening cement-bonded particle boards must be suitable for the cross-section of the beams and the material from which they are constructed. This leveling method is used only if the difference in level differences is more than 6 cm; raising the level with the help of canvases is permissible on average to a height of 7 to 10 cm.

DSP plate, specifications which will be presented in the article, is used quite often today. It is distinguished by outstanding qualities that have made the material widespread in private and professional construction.

Characteristics of DSP slabs

Due to the fact that the described material has excellent characteristics, it is widely used in various fields of construction. Cement particle board contains wood shavings, Portland cement, and special additives, the latter of which can provide excellent protective qualities. During the production process, all of the listed components are combined and then mixed until a homogeneous mass is obtained. Then the composition is pressed.

Products are manufactured in accordance with GOST, which strictly regulate the composition. Thus, the components should include 65% Portland cement, 24% wood chips, 8.5% water, and 2.5% impurities. Density is ensured by the presence of Portland cement in the composition, the same component guarantees the durability of the material. The production of slabs is carried out on special equipment in a factory environment, as evidenced by a quality certificate, as well as a product passport. The boards contain natural wood, which ensures the environmental friendliness of the material. This indicates that the stove is completely harmless to humans.

Positive features of DSP

The DSP board, the technical characteristics of which must be known before purchasing, is of excellent quality, which allows the use of this material in professional construction. Technological processes The manufacture of plates is based on the mineralization and bonding of all components, so the appearance of a radioactive background, the release of steam, dirt or dust can be completely eliminated.

DSP boards are actively used in the construction of strong and warm housing. Quite often this material is compared with others. The slabs described are so durable that they win in this comparison. Their service life is much longer.
Additional advantages include excellent resistance to temperature changes and frost, which meets the requirements for modern building materials.

The DSP board, the technical characteristics of which are described in the article, has proven itself to be excellent. These products do an excellent job of repelling rodents, insects, as well as mold and mildew. The material does not contain phenol, asbestos, impurities or formaldehyde resins. These slabs can be used for all types of finishes. The surface of the slabs can be plastered, finished with plastic, painted, tiled, covered with various decorative materials, etc. It is easy to use this material, as it is easy to process. It contains a large amount of shavings, this makes the product look like natural wood, but these boards are highly durable. You can use DSP for the construction of partitions, which will have excellent sound insulation qualities. DSP walls will be able to provide sound absorption of up to 30 dB.

Strength characteristics of CBPB

DSPs whose technical characteristics differ from others alternative materials, have high density. This is due to the fact that the chip pressing method is used during the production process. The inner layers of the product contain fibers that have a longer length. This guarantees the material excellent elasticity, smoothness, and high strength characteristics. The material has several layers, so it is able to combat moisture. Special technology, used in production, does not allow the product to delaminate. The slab will not break, even if it is subjected to mechanical force such as bending. The material copes well with high loads; during operation, it can be subject to mechanical impacts, which makes such slabs so widespread and popular in construction.

Cost of DSP

DSP is a slab, technical characteristics, the price of which should interest you if you plan to use this material in construction, may have different sizes. The most traditional dimensions are 1250x2700 mm. the cost of such a sheet will be 675 rubles. This cost can be called very affordable, which makes this material so popular among analogues. Despite the fact that the cost of the stove is quite low, its quality remains excellent.

Dimensions of DSP

The CBPB board, the technical characteristics of which must be indicated in the quality passport, must be examined by the consumer before purchase. It is important to take into account the size range of these products. The slab can have a width of 1250 mm or 1200 mm. The latter standard is considered modern. But despite this, slabs are still produced different sizes. The length can be equal to 2700 mm, while the thickness is equivalent to 8 mm. This product weighs 36 kg. If the thickness is increased to 10 mm, the weight will be 46 kg. A thickness of 12 mm increases the weight to 50 kg, and a thickness of 16 mm increases the weight to 74 kg. A plate thickness of 18 mm makes the mass equal to 81 kg.

With a slab length of 3200 mm, the thickness can be 8 mm, while the weight of the slab is 43 kg; with a thickness of 10 mm the weight will be 54 kg, while a thickness of 12 mm gives a weight of 65 kg.

The standard size is 1200 mm. A slab with a length of 2700 mm can have a thickness of 8 mm and a weight of 35 kg. A slab thickness of 10 mm gives a mass of 44 kg. Among other things, the buyer can purchase a slab that has been manufactured to specific dimensions. The length of the slab can be 3600 mm or 3000 mm. You should not look for products on sale whose edges have a semicircular shape, since such slabs are not produced. Also, products with thinner edges are not produced in a factory. Once the slab has been purchased, it will not need to be treated with an antiseptic, since the products are antiseptic at the factory.

Scope of application of DSP

The DSP board, the technical characteristics of which must be studied before making a purchase, is used today in housing construction. Products are capable of providing internal protection by cold. This material can be used when covering walls made of concrete. Products are used in low-rise construction, as well as in the construction of buildings special purpose. DSP is excellent for rooms where conditions are characterized by high levels of humidity. After the slab is installed, its surface does not need to be treated. It will only be enough to coat the surface with a primer or a composition that has water-repellent characteristics. Buildings that use DSP can withstand severe operational loads.

Additional product applications

The DSP board, the technical characteristics of which can be found in this article, is also used for permanent formwork equipment, which makes it possible to achieve excellent results. At the same time, some positive features can be highlighted, among them: reducing the period of construction work, reducing the amount of construction costs, as well as ensuring reliability and strength future design. The DSP board, the technical characteristics, the use of which made the products popular, is also used today in the manufacture of window sills. Moreover, the latter are not only durable, but also quite inexpensive compared to analogues. You should not assume that due to the insignificant cost of the DSP, the window sill will have a very unsightly and unpresentable appearance. Such products have excellent decorative qualities and resemble expensive window sills made of noble materials.

For comparison with other materials, we suggest using characteristics such as:

• fire safety;
• ease of installation;
• resistance to mold and disease;
• builder reviews;
• reviews from residents and home owners.

Fire safety and flammability class

That's why DSP parameter superior not only to polymer insulation and PVC, but even wood concrete. DSP is assigned a flammability class - G1, that is, they are difficult to burn. Due to the large proportion of cement, each of the shavings is surrounded by cement stone, so to start the pyrolysis process in wood located close to the surface exposure to temperatures of 500 degrees or more for half an hour is required.

Once the thermal effect is removed, the pyrolysis process is quickly completed, because close contact of many chips is necessary for the self-sustaining reaction to begin.

If the temperature exceeds 700 degrees, and this effect lasts for over an hour, then pyrolysis of the chips begins throughout the entire depth of the slab.

At this temperature any Construction Materials sharply lose strength, and the concrete completely collapses. Therefore, after a fire of such magnitude, the house cannot be repaired, unless the fire was local in nature and burned only a small area of ​​the house.

Even the beginning of the pyrolysis process does not lead to the release of particularly toxic substances, because the main components of pyrolysis gas (smoke) are:

• nitrogen;
• carbon dioxide;
• carbon monoxide.

Only carbon monoxide poses a serious danger, but, firstly, very little of it is released during the pyrolysis process, and secondly, during a fire, combustion occurs in conditions of lack of oxygen, so carbon monoxide is released everywhere in huge quantities.

Therefore, DSP one of the safest in terms of fire resistance of materials and is comparable to gypsum plasterboard and fiberboards. It is much safer than finishing from:

• plywood;
• boards;
• wood concrete;
• insulating fiberboards;
• foams and plastics.

Ease of installation

Due to the high cement content of CBPB much heavier than most others finishing materials.

The weight of thin sheets is 25–45 kg, so a minimum of 2 people are required to work with them.

To work with thick sheets, 5-6 people are needed, because the weight of a sheet with a thickness of 26 mm exceeds 200 kg.

Cutting the material is also fraught with difficulties, because it is necessary to use high-speed circular saw and diamond-coated blade or carbide tipped.

Therefore, in terms of ease of installation, DSP is inferior to most finishing materials. After all, its weight, with equal dimensions and thickness, exceeds the weight of any other finishing material, including LSU and wood concrete.

Resistant to mold and disease

Due to the fact that the wood in CBPB does not have direct contact with air, it is less susceptible to mold and disease.

In addition, for products manufactured in accordance with GOST requirements, the chips are pre-soaked in a solution of lime or other reagents, increasing biological stability wood

Reviews from builders and residents about wood-cement blocks

To collect the most reliable reviews about the characteristics, application and prices of DSPs, we turned to forums, whose users include:

Application of DSP for flooring

When laying DSP on the floor along joists, it is recommended to choose a product thickness of 24 mm or more to ensure sufficient strength of the floor covering.

Fastening by joists

When working indoors, it is necessary to carry out preparatory measures - seal holes in the base, if any, fix the logs, put insulation and vapor barrier material.

Preparatory work before laying CBPB on the floor

The slabs are fixed using self-tapping screws, and the screw with a countersunk head should be immersed into the body of the wooden beam by 20 mm. The result is a perfectly level subfloor with excellent performance characteristics.

Frame construction

DSPs have proven themselves to be excellent in the construction of frame-type houses. There are two options - purchasing a ready-made house kit from SIP panels based on DSP or self-construction walls between which is located mineral insulation. The slabs are fixed using wooden or metal sheathing, the frame is sewn up around the perimeter, and then the window and doorways. The sheathing elements are installed in 60 cm increments so that the insulating material can be firmly fixed between them. Plates are taken 10–16 mm thick and fixed with galvanized screws.

Interior finishing works

The environmental safety of cement particle boards has made it possible to use them as a full-fledged finishing material indoors for any purpose. Due to its high moisture resistance, this material has significantly replaced plasterboard, which is not recommended for use on walls in wet rooms.

Leveling the walls and floor in the bathroom

DSPs are used for effective leveling of walls and their subsequent finishing with decorative finishing materials. However, in some interiors (loft, industrial, high-tech and others), where a raw concrete texture is appropriate, DSP is used to create accent surfaces and even to cover entire rooms.

The accent wall in the bedroom at the head of the bed is made of cement panels

Fastening the plates depends on the thickness and dimensions of the sheets, and, accordingly, their weight. Heavy products are fastened along the sheathing, and light ones are secured using a special solution or mastic.

Production of SIP panels from DSP

SIP panels made of DSP are a three-layer material, where insulation made of expanded polystyrene, basalt fiber or polyurethane foam (PPU) is fixed between the sheets.

Appearance of sandwich panels

A common distinguishing feature of the material is its high fire and environmental safety. Opportunity rapid construction private house and significant savings on facade finishing works.

Application of DSP for formwork in monolithic construction

There are a number of advantages of installing permanent formwork of this type when producing monolithic works:

1. Reduction of installation work and the overall construction period of the facility.
2. The surface is ready for finishing.
3. High profitability of the construction of the facility as a whole.
4. Guarantee of a strong and reliable structure.

Monolithic construction using permanent DSP formwork

Installation methods

DSPs can be mounted in various ways depending on the purpose for which they are used. When finishing or insulating buildings, they are attached to a sheathing made of metal profile or wooden blocks, self-tapping bolts or nails. The installation of permanent formwork also involves erection of the frame (given the large weight of the slabs, it, like the sheathing when finishing the walls, must be strong enough). In addition, the slabs can be laid on joists (when installing the floor) or rafters (under the roofing). For interior decoration they are also can be attached to the wall with mortar or mastic.

Preparing for the installation of a DSP coating

Before starting construction work rough coating The base of the floor made from CBPB must be properly prepared. For example, in the case of laying material on wooden base old or rotten boards must be dismantled and replaced with new ones

It is important to seal all the cracks with putty, and the wooden base is primed for better adhesion to the glue on which the slab covering will be mounted.

If installation will be carried out on concrete base, then it must also be carefully inspected for damage and repaired if necessary. Also, if there are strong horizontal deviations, leveling is done with cement mixtures. When laying CBPB on the ground, it is necessary to first level the surface - this can be done by pouring a 20 cm thick sand-gravel mixture onto the ground and compacting it.

The process of building a gazebo with a DSP floor

The best option is to lay CBPB slabs on logs. In this case, if it is planned to install the foundation directly above the ground, supports for the logs are installed on the ground, and hydro- and thermal insulation is also laid. The distance between the supports can vary from 0.5 to 1 m - this indicator depends on the thickness of the timber used for the logs.

Materials and tools that need to be prepared for working with DSP:

• timber for logs (section 150x100 or 50x100 mm);
• DSP boards in the required quantity;
• antiseptic solution for timber;
• sawing tool (for example, a hacksaw);
• materials for waterproofing and insulation;
• tools for taking measurements (tape measure, pencil);
• fastening material;
• drill.

How to paint a DSP board

To give the DSP boards an attractive appearance most in a simple way is coloring. After appropriate preparation of the surface, apply two layers of paint using a roller or. Most often, in order to paint DSP, they use:

Acrylic paints . This paint has good adhesion and is highly wear-resistant. If financial capabilities allow, it is better to use paints that contain a solvent, but water-soluble facade acrylic paints, if applied correctly, will last from 3 to 5 years.

Latex paint . This coating is resistant to alkaline and weak acid solutions and is easy to wash and mechanically clean with detergents. Besides. You can do the painting work yourself, which will save you a significant amount.

Silicate paint . The use of this type of coating has high adhesion, their vapor permeability provides optimal conditions for air circulation, which prevents the appearance of mold and other fungi. The coating is not afraid of atmospheric influences and detergents, and the service life will satisfy even the highest requirements.

Before you begin painting DSP, it is necessary to take into account that the use of alkyd paints is undesirable, since direct contact with alkalis may cause cracking and peeling of the coating.

1 What are such slabs made of? Are additives needed?

DSP is a multi-component sheet building material, the manufacturing process of which uses Portland cement and wood shavings. In addition, the board contains special chemical additives that allow the basic materials to coexist without any problems. Indeed, under normal conditions, wood is not friendly with cement, which provokes excessive moisture and associated warping and rotting of the material.

Portland cement and shavings are used for the manufacture of CBPB

The use of special additives (up to 2.5–3% of the total volume) eliminates the negative consequences of the proximity of wood and cement, giving the CBPB such beneficial features the first and second components, such as heat resistance and fire resistance. Moreover, due to the percentage ratio - 24% of wood accounts for 65% of cement - the slab also acquires other positive traits: high strength, frost resistance, soundproofing properties, vapor permeability and complete ignoring of the material by both insects and rodents.

In addition, both wooden and cement board demonstrates such qualities as resistance to fungi, moisture resistance, resistance to thermal shrinkage and compatibility with most finishing materials, which is explained by enviable adhesion. At the same time, chemical additives in CBPB are not environmentally friendly harmful materials, since they do not contain either asbestos or formaldehyde.

Technical characteristics of DSP

During manufacturing, high-strength cement compositions are mixed with wood shavings of various fractions, water and a number of chemical reagents (for example, liquid glass or aluminum salts). By reacting with wood shavings, chemicals mineralize them, thereby increasing the strength and durability of the slab.

Multi-layering is the main quality of the slabs, guaranteeing their high quality and special strength. The structure of the slab is formed in such a way that large fractions of chips are located inside, and small fractions are located outside. After preparing the cement-bonded particle board, it is placed in layers in special molds under a press, from where the finished multilayer CBPB with a smooth surface on one side comes out.

DSP: the technical characteristics of the board are such that it does not require the application of finishing putty. It is enough to paint the slabs after placement. In some cases, applying a thin coat of primer before painting will be sufficient.

DSP floors: laying nuances

In general, the installation of CBPB slabs is carried out in exactly the same way as the installation of OSB slabs.

When carrying out work, it is important to follow several rules, and then the base of the floor will be made of the highest quality possible: . wooden beams for logs must be treated with compounds that prevent rotting

Special compounds can be replaced with machine oil;

• wooden beams for logs must be treated with compounds that prevent rotting. Special compounds can be replaced with machine oil;

Antiseptics for wood impregnation

• When installing slabs on a concrete screed, beams of a smaller cross-section can be used for logs - up to 50x50 mm. This will save useful space;
• when installing logs, you should monitor their level - it must be strictly horizontal;
• before installation, the CBPB boards are laid out along the joists - this will allow you to determine which of them need trimming if necessary;
• the glue must be mixed well before use;
• Compensation gaps along the walls will allow you to avoid deformation of the DSP base.

Another example of the use of DSP

DSP is a pretty good material if you use it to create a flat base. It is not difficult to work with it, but due to the large mass of sheets, it is better to get an assistant.

Installation features

Slabs based on a cement-bonded particle mixture are easy to process. For cutting you will need a hacksaw with fine teeth. Large teeth contribute to the formation of dust and make the edges of the part uneven, so this tool is not suitable for sawing CBPB.

When arranging a dry screed, a concrete or wooden covering is used as a base for the slabs. It is also possible to lay sheets on a frame, the cells of which are pre-filled insulation material(mineral wool, foam plastic, expanded clay, other types of dry filler).

The plates are fixed with self-tapping screws or using glue mixture. The glue must be evenly distributed over the surface of the material with a notched trowel, leaving no gaps. This will help avoid deformation of the material.

It is also important to generously fill the joints with adhesive to obtain a monolith. Self-tapping screws are screwed in at intervals of 35-50 cm

When cladding the external walls of a building with DSP, an installation method is used that involves arranging sheathing. Frame parts can be wooden or made of metal profiles. When choosing a tree, it is recommended to pre-treat it with an antiseptic solution to protect it from premature aging and microbiological processes.

To create thermal protection for a home, it is recommended to lay thermal insulation material between the walls of the house and the DSP. Preference should be given basalt wool, which has a good indicator of vapor permeability (the walls will breathe) and high resistance to moisture (low hygroscopicity will prevent the absorption of moisture into the layers of heat insulation).

The finishing of slabs made of cement-bonded particle board involves treating the surface with a primer, laying a reinforcing mesh and applying a layer of decorative plaster. The facade is painted in a color that echoes other architectural elements of the exterior.

Arrangement of the floor using DSP

Let's consider the arrangement of a floor made of cement-bonded fiberboard on joists using the example of a balcony.

Step 1. A layer of insulation is placed under the joists. The logs are installed parallel to the walls at a distance of about 30-40 cm from each other.

The joists are installed on top of the insulation

Step 2. Cross bars are installed and the sheathing is created. Between themselves wooden blocks connected using metal corners and self-tapping screws.

Cross bars installed, sheathing ready

Step 3. The space between the joists is filled with insulating material.

Laying insulation

Step 4. DSP slabs of the required sizes are laid across the longitudinal joists. The width of the piece of material should be slightly less than the width of the balcony (by 5-10 mm).

Laying CBPB boards

Step 5. The slabs are fastened with self-tapping screws to the joists. The gaps between the DSP boards are sealed with an adhesive composition.

DSP in the process of creating the foundation

Slabs based on cement and shavings can be used to create formwork, which helps when pouring the foundation. The thickness of the material depends on the required dimensions of the foundation and ranges from 16 to 26 mm.

Strengths of DSP formwork.

The ease of installation of slabs reduces labor costs by an order of magnitude and shortens the time required for work, thus reducing the cost of pouring the foundation. You can apply a special paint to the outside, after which it will acquire the properties vertical waterproofing. Due to the high strength of the slabs, the formwork is resistant to deformation during pouring and drying of the concrete solution.

The versatility of DSP allows this material to be used in the construction of housing based on a frame, for leveling floor and wall coverings, as well as during installation soft roof in buildings of any type. DSP flooring boards receive good reviews from builders around the world due to the high quality of the material and excellent characteristics.

Cement particle board application for flooring

The main advantages of DSP are considered to be high strength and durability

The use of building materials consists of laying finished panels on various types of bases:

• a flat surface of a wooden or cement floor;
• wooden logs installed at equal intervals.

Ceramic tiles can be glued to the surface of the slabs, flooring can be laid, and laminate or parquet can be laid. The properties of the material are preserved for decades, provided that the installation technology is followed.

Scope of application of CBPB boards

As mentioned above, DSP boards, the use of which ensures high mechanical strength of the structures being created, are widely used in construction, repair and finishing works ah, in particular:

• In the manufacture of formwork foundations and other monolithic reinforced structures. The use of DSP significantly simplifies the installation process; in addition, this design prevents concrete leakage and ensures the formation of smooth side walls that do not require subsequent plastering.
• When covering walls and erecting . In most cases, DSP sheets are attached to a pre-assembled metal or wooden frame. The thickness of the sheets in this case ranges from 8 to 12 mm. For fastening, self-tapping screws are most often used; it is also possible to use screws or nails as fasteners. In some cases, when leveling walls, special adhesive polymer mixtures can be used.
• Application of DSP boards for flooring provides high mechanical strength, as well as high thermal, hydro and sound insulation. The thickness of the material is selected based on the current loads and the distance between the lags, however, the use of CBPB boards with a thickness of less than 14 mm is not recommended.
• Application for facade at home allows not only to significantly reduce the time required for work on exterior decoration, but also provides high-quality waterproofing of the main walls. Another advantage is that when using DSP, the characteristics of the material allow you to create various types of ventilated facades. As for the sheet thickness, for outdoor use it can vary from 12 to 14 mm.

Slab production

The production of CBPB consists of the following stages:

1. Aluminum, liquid glass, and various salts are included in aqueous solutions that are loaded into special mixers.
2. Mineralization of raw materials occurs with the gradual introduction of wood chips, consisting of different-sized fractional inclusions, into these solutions.
3. Then cement and a little water are added to the composition.
4. The mass is thoroughly mixed to obtain a homogeneous consistency and sent under a powerful press.
5. The result is a thin but durable product with a smooth surface.

The smooth surface of the slab is obtained due to the special distribution of chips in its structure - larger fragments are located inside the product, and small ones are on the surface. During the production of CBPBs, there are no voids in them. Another advantage is that the product does not require additional leveling, but can be immediately used to make a subfloor and serve as a high-quality, even base for laminate, tiles and other types of finishing coating.

DSP production technology

From the name itself it becomes clear that the main components of this material are cement (65%) and wood shavings (24%). All this is mixed with water (8.5%), and various additives are added to the resulting mixture to improve the technical characteristics of the slab (2.5%).

In the process of producing CBPB, two types of particle boards are used. They differ in size: small and medium. The slab itself has a three-layer structure, so medium-sized chips are poured into the second layer, and small chips into the first and third. The production process itself takes place in the following sequence.

• The shavings are mixed with hydration additives.
• Cement grade M500 is added to the resulting mixture.
• Water is pouring in.
• The solution is thoroughly mixed until a homogeneous mass is obtained.
• The first layer of fine chips is poured into the mold.
• The second layer with medium-sized shavings.
• And the third layer.
• Pressing is in progress.
• After which the semi-finished material is heated to +90C for eight hours.
• Then it is dried under natural conditions for 13-15 days.
• After which, depending on the batch, it is either polished or simply stored.

Cement particle boards used in construction

DSP is a cement-bonded particle board, and the name fully reflects the composition of this material. DSPs are made from a mixture whose components are wood shavings and cement compounds.

What are DSP and OSB? What is the difference?

The building materials include:

• wood shavings with fractions various sizes – 24%;
• water – 8.5%;
• special additives – 2.5%;
• Portland cement – ​​65%.

DSP boards for external use

The production process is quite simple - DSP is made as follows.

1. Special aqueous solutions are loaded into special mixers, which include various salts, liquid glass and aluminum.
2. Next, wood shavings with fractions of different sizes are gradually added to these solutions - mineralization of the raw material occurs.
3. Cement is mixed into the resulting composition and a little more water is added.
4. The mass is thoroughly mixed until smooth and then goes under a powerful press.

GOST 26816-86

The result of this production chain is a finished cement bonded particle board, which is quite thin and has a smooth surface. A large amount of cement in the composition allows you to create a fairly durable material. By the way, inside the slab the chips have O larger dimensions than outside, due to which a smooth surface is achieved finished material. DSP does not need to be further leveled after installation, making the material excellent for creating a rough floor covering for laminate, tile and other types of finishing. Also, no voids are formed inside the DSP during production.

Production of cement particle boards

On a note! Wood shavings are also used as raw materials for chipboard production, fiberboard and OSB boards. The technologies for producing these materials are somewhat similar to the technology for producing CBPB boards.

Comparative table of performance characteristics of wood-based materials

DSP boards are widely used in construction. They can be used to decorate the facade walls of houses, they are used to create various partitions indoors. The material is suitable for use for restoration purposes and for interior finishing work. Moreover, it is suitable for both apartments and private houses.

DSPs are used in construction for many purposes

The DSP board is characterized by high environmental friendliness, as it is created from natural natural materials and contains virtually no additional chemical ingredients. That is why the stove is recommended for use both in residential premises and in production.

Cement particle board (CSP)

Using a cement bonded particle board is an opportunity to avoid labor-intensive pouring cement screed to create a foundation. The building material allows you to reduce labor costs and spend less money from the budget planned for leveling floors for laying the finishing coating.

Installation of a DSP board under ceramic tiles

Rules for processing what can be used to saw and drill CBPB boards

Whatever one may say, CSP is a concrete stone filled with shavings (wood filler). Therefore, when the question is raised about how to process the material of this type, cannot be mentioned hand tool. Cutting and drilling can only be carried out with electric tools.

In this case, it is better not to use a jigsaw, although some craftsmen manage to cut thin slabs with this tool. You just have to change the file often - every 5-7 m. Therefore optimal solution– disk cutting tool.

The easiest way to cut CBPB is with a circular saw with a diamond blade.

As for the disk, there are two options:

1. Diamond coated disc with cut out segments. This disc is used for dry cutting. Here you can use discs for cutting stone, concrete or brick - they will all work.
2. Discs coated with pobedite, used for cutting wood. DSP is not the strongest material compared to stone, so this tool can handle it.

As for power tools, most often craftsmen use an angle grinder or a circular saw (parquet).

Attention! It is easier to cut CBPB boards with a circular saw because the power tool has a support bar. It is this that allows you to clearly orient the disk in a plane perpendicular to the sheet, and the final result is an even cut of the material

DSP boards can be cut with a grinder with a diamond cutting disc installed on it

As for drilling holes in slabs, either metal drills or pobedit drills are used for this.

Types and characteristics

There are 3 types of DSP:

• fiberboard– heat-insulating material based on long-fiber shavings (“wood wool”). Soft, easy to process, resistant to biological factors;
• wood concrete– made from sawdust and small shavings. It has a wide range of applications (thermal insulation, finishing, material for wall partitions, etc.);
• xylolite(slab and cast). Has high strength, thermal insulation qualities and a wide range of colors, used as flooring.

Due to their water absorption, the slabs increase in size, so when installing, a gap is required between them

Kinds

There are three types of DSP. Studies of the material have accurately shown that each of them does not lose its valuable properties even during multiple cycles of significant temperature increases and subsequent defrosting.

Resistance to fire and particularly humid environments, as well as negative biological factors, was also confirmed. But each type of slab has its own characteristics, consisting in the method of production, differences starting materials, characteristics of finished products and scope of application. Among the types you can indicate.

1. Fiberboard. Its basis is the so-called wood wool, which is long-fiber shavings. The composition also includes inorganic binders.

Wood strips produced on special machines are impregnated with solutions of calcium chloride and liquid glass. The raw materials are pressed into molds and subsequently dried. The thickness of such slabs can reach 150 mm, but there are a number of much thinner parameters.

These building elements, with their considerable strength, are excellent for thermal insulation. A similar material is also used as an acoustic material.

It is easy to process and soft, for this reason it is in demand for multifaceted repairs, as well as reconstruction work of various structures. During construction operations with slabs, due to their low weight, lifting equipment is not required, and therefore their use is very economical.

2. Wood concrete. It is classified as lightweight concrete and contains small shavings, sawdust, reed chaff or rice straw. The highest quality slabs of this variety are made from wood chips.

If the basis of the composition is wood shavings, then the material is usually called wood concrete, if sawdust - sawdust concrete. The two types mentioned have slightly reduced performance characteristics compared to the first one mentioned above.

They are heavier, denser and subject to unpleasant deformations, but they are also somewhat cheaper. The scope of application of wood concrete is quite wide. But mainly it is in demand as a material for low-rise private construction, especially popular in the manufacture of wall partitions, also for finishing and thermal insulation.

3. Xylolite is most often known in application as a coating. DSP for flooring. Plates, similar to those previously described, are made from wood waste, differing from other types in production technology. On sale, the presented assortment pleases with a variety of colors.

The material is distinguished by excellent thermal insulation qualities and increased strength. It does not burn in an open fire, but only gradually chars; even when boiling, it does not get wet in water and is only slightly thermally conductive; It has enviable elasticity and is hard like stone, but at the same time it is easily processed like wood: drilled, planed and sawed. In addition to the above, it is ideal for use as cladding for stone, covering stairs, window sills, and roofs.

An important characteristic is the weight of the DSP board. Such indicators are simply necessary to know during construction and other work.

The specified data is very useful during cargo transportation and during installation work. The mass of one module directly depends on the thickness and, knowing this indicator, it is easy to calculate. After all, for every 10 mm there is approximately 54 kg of tile weight.

Installation work: how to cut DSP

You shouldn’t try to cut CBPB with a hacksaw - it’s a thankless task, the process is long, and the result leaves much to be desired. You can use a jigsaw or grinder.

Article

Among the slab and sheet materials used for finishing and constructing partitions and various design elements, one cannot ignore cement-bonded particle board or cement-bonded particleboard. Of course, in terms of popularity it is inferior to drywall, but, as practice shows, it is also suitable modern world there is a place. Most often, the DSP board is used by builders as formwork. It is smooth, with good strength, plus - with its help, it is much faster to assemble formwork than from boards.

Many may doubt that the use of DSP is advisable for the construction of formwork. After all, it can be replaced, for example, by metal or plywood, which are also used. This is probably true, but a slab with a thickness of 24-26 mm can withstand quite serious loads. In addition, if you install permanent formwork using cement-bonded bonding material, then, in fact, you will get a finished foundation or other structural element building. And this is a big plus in many situations.

In addition, it is necessary to take into account the conditions under which the room being finished will be used. For example, if this is a gym, then there can be no talk of any drywall. He just can't withstand the ball's impact. And the DSP boards will hold up. They can be used for strapping and cladding frame houses. Better than this material for given value Can't find it today. The advantage is the ability not only to paint cement-bonded bonding material, but also use it like finishing. Fortunately, manufacturers today offer a huge assortment with designs for different materials, as shown in the photo above.

DSP production technology

From the name itself it becomes clear that the main components of this material are cement (65%) and wood shavings (24%). All this is mixed with water (8.5%), and various additives are added to the resulting mixture to improve the technical characteristics of the slab (2.5%).

In the process of producing CBPB, two types of particle boards are used. They differ in size: small and medium. The slab itself has a three-layer structure, so medium-sized chips are poured into the second layer, and small chips into the first and third. The production process itself takes place in the following sequence.

• The shavings are mixed with hydration additives.
• Cement grade M500 is added to the resulting mixture.
• Water is pouring in.
• The solution is thoroughly mixed until a homogeneous mass is obtained.
• The first layer of fine chips is poured into the mold.
• The second layer with medium-sized shavings.
• And the third layer.
• Pressing is in progress.
• After which the semi-finished material is heated to +90C for eight hours.
• Then it is dried under natural conditions for 13-15 days.
• After which, depending on the batch, it is either polished or simply stored.

Specifications

The fact that this is a durable material is clear because it contains a cement component. But it is also moisture resistant due to the use of hydration components. Plus, DSP boards have excellent load-bearing capacity, which cannot be said about gypsum board or plywood. But a lot will depend on the parameters of the stove.

As for the width, it is standard - 1.2 m. But the thickness and length are dimensions that vary over a fairly wide range. As for the length, the manufacturer can cut it to any size if the order batch is large. But there are also standard values: 2.7; 3.0; 3.2 and 3.6 m.

As for thickness, there is a fairly decent range here too: from 8 to 40 mm. Accordingly, the weight of the product will increase with increasing thickness. For example, a slab 2.7 m long and 8 mm thick weighs 35 kg. With a thickness of 40 mm, the weight will increase to 176 kg.

With a DSP length of 3.2 m and a thickness of 8 mm, its weight will be 41 kg. With the same length and thickness of 24 mm, the weight will be 124 kg.

There are no rounded edges or chamfers in the design of the DSP boards. The edges are straight and cleanly cut, so there shouldn't be any problems with joining panels and fitting. They do not need to be treated with antiseptic compounds before finishing, because during the manufacturing process an antiseptic is added to the raw solution.

Other technical characteristics according to GOST:

• Withstands large subzero temperatures. In this case, the defrosting process can occur up to 50 times. After which the strength of the slabs decreases by only 10%.
• The error on the outer plane is 0.8 mm.
• The difference in the lengths of the diagonals can be 0.2%. This is practically no more than 5 mm for a length of 2.7 m.
• Thickness error (permissible) is no more than 0.8 mm. This is for unsanded material, for sanded material 0.3 mm.
• Water absorption is 16%, while per day at high humidity the slab should not increase in size by more than 2%.
• Withstand tensile loads - 0.4 MPa, bending loads 9-12 MPa, depending on the thickness of the product. The thicker it is, the less it can withstand bending loads.

Manufacturers today offer two types of cement-bonded particleboard material, which differ from each other in quality characteristics. These are TsSP-1 and TsSP-2. The first one is better.

There is an opinion that slabs of this type are inferior to plasterboard in many respects. You should not compare these two materials, they have different purposes And different areas applications. The examples described above confirm this. Of course, DSP has its drawbacks, which we’ll talk about.

• Compared to plasterboard, cement-bonded particle boards cost almost twice as much. But gypsum board cannot be used for exterior decoration, and it’s better not to sheathe a frame house with it.
• The weight of each slab can be terrifying, especially those with a thickness of more than 16 mm. You won't be able to work with them alone. Under them you will have to build a strong and reliable frame. And the foundation will have to be strengthened if they are used to cover a frame structure.
• In addition, the cement component gives the material increased strength, so it is difficult to process. Therefore, pruning should be done with a grinder or manual circular saw, but it’s not easy to use cutting tool, but diamond.
• The frame has already been mentioned, but it must be added that profiles for plasterboard are not suitable here, especially if we are talking about external finishing with DSP boards. A standard steel profile is required here.
• When cutting slabs, a large amount of dust is released, so this operation should only be performed outdoors.

Cement particle board is a relatively new building material with a universal scope of application. Has completely natural base, DSP sheets do not burn, are not afraid of moisture, are resistant to most external influences and require minimal protective finishing. Reviews are mostly positive; owners of private houses classify them as budget ones. The only significant limitation is the high specific gravity, on average it is 1300 kg/m3, which makes independent installation difficult.

The material has the form of flat slabs with a dense and uniform structure of gray-brown color. The basis of CBPB is cement and wood shavings (65 and 24%, respectively), 8-8.5% of the volume of raw materials is water, the remaining 2.5% is hydration additives to reduce the moisture concentration in the final product (for example, aluminum sulfates). There are no harmful impurities, the cement particle board does not contain asbestos, formaldehyde or phenols. At the same time, it is highly resistant to biological influences, formed by cement. alkaline environment protects chips from rotting, fungus, insects and even rodents. For the same reason, it is not afraid of fire, despite the natural wood.

Technical characteristics of CBPBs and their dimensions are regulated by GOST 26816-86. The main indicators include:

• Density – within 1100-1400 kg/m3, standard value is 1300.
• Humidity – 9±3%.
• Water absorption by volume over 24 hours is no more than 16%.
• Flammability group – G1.
• Bending strength, depending on the thickness of the slabs, is at least 9-12 MPa, and compressive strength is within 0.4.
• Thermal conductivity coefficient is 0.26 W/m K.
• Vapor permeability is 0.03 mg/m·h·Pa, which justifies the use of such slabs indoors.
• Deterioration in strength characteristics after 50 cycles of freezing and thawing is no more than 10%.

DSP has standard sizes: 2700 or 3200 mm in length, 1200 or 1250 in width, thickness varies from 8 to 40 mm. The surface of the slabs can be smooth or embossed; the roughness of polished products is zero. The permissible deviation in length and width does not exceed ±3 mm, in thickness - ±1.4 for the thickest sheets. Reviews confirm the high geometric accuracy of the slabs; their decorative and insulating properties are positively assessed (noise absorption indoors reaches 30 dB).

Use in construction: pros and cons

The main limitation in the use of cement bonded particle boards is their high specific gravity. With equal sizes, they are at least twice as inferior to chipboard and other sheet building materials in this regard. The use of DSP automatically implies an increase in the load on the foundation and bearing structures, increasing requirements for the reliability of the frame and fasteners, difficulties in transporting them to the upper areas. One medium-thick slab weighs at least 80 kg; installation by one person is impossible, as is lifting to the second floor without scaffolding and winches.

Cutting and further processing are possible at home, but you should be prepared for the formation of dust. DSPs are classified as abrasive materials with strength characteristics similar to dense wood, such purposes imply the use of tools with high speeds and hard working surfaces. On the other hand, according to reviews, there are no problems with drilling, fastening and subsequent finishing; the edges when cutting are neat in any case.

Overall, the advantages outweigh the disadvantages. The advantages include:

• Environmental safety.
• Versatility and multifunctionality.
• Compliance with fire safety standards: flame does not spread across the surface of the DSP, the material does not emit smoke and toxic substances when exposed to high temperatures, the fire resistance limit is 50 minutes.
• Long term maintenance-free operation; under normal conditions, durability reaches 50 years.
• Geometric accuracy of shapes. These products are certified; the dimensional characteristics of cement particle boards are controlled by GOST. Stability of shapes is maintained throughout the entire service life; DSPs are not afraid of UV or temperature changes. Fracture is possible only when installed on an uneven surface.
• Independence from climatic conditions.
• Good insulating properties, applications include multi-layer structures.
• Resistant to moisture and rot.
• Vapor permeability allowing you to breathe.

The main criterion is the thickness of the slabs; it is selected taking into account their intended purpose. In particular, the recommended limit for different building structures is, mm:

• When installing formwork - 12-24.
• For slabs for cladding facades and interior decoration walls – 10,12 and 16.
• When constructing moisture-resistant partitions - 12 and 16.
• Using DSP as a window sill – from 24.
• When using floor slabs (rough, base for other building materials, leveling layer or finishing) - from 8 to 24.

The higher the expected loads (including humidity), the thicker the DSP is needed. At the same time, an increase in this size characteristic leads to an inevitable increase in weight, which is not always acceptable. This also applies to the cost of material: prices for chipboards of various sizes, but the same in area, vary from 600 to 2,500 rubles with a thickness of 8 and 36 mm, respectively.

The next factor to be taken into account is the type of surface of the slabs; plaster fits equally well on both embossed and smooth varieties, but when painting, the use of the latter is preferable. Textured DSPs are optimal for internal decorative finishing. Attention is drawn to the compliance of the characteristics of the board with GOST; in this regard, it is better not to take risks and purchase products from trusted manufacturers. Products from Russian factories Tamak (Tambov), TsSP-Svir (St. Petersburg), Stropan (Omsk), MTI CJSC (Kostroma), Sterlitamak (Bashkorstan) have positive reviews. Their price offers are almost the same; the final cost is affected by the proximity of the warehouse and the volume of purchases.

Review Reviews

“During the construction of the garage, a leveling cement-sand mixture, about 3-5 cm, was poured onto the compacted earthen floor, and after hardening, I placed 26 mm thick CBPB sheets on top. I gave it a year to shrink, during which time the floor was used. I didn’t find any deflections, breaks or places where the material was rotting, the surface remained smooth, and eventually I covered it with tiles. There are no complaints about the quality."

Alexander, Moscow region.

“Four years ago I was building a house outside the city frame method. A builder I know highly praised this rather new material for our market and decided to buy it for external and interior walls and gender. For the facade and rough flooring I used cement bonded particle boards 24 mm thick, for the interior cladding and ceiling 20 and 10 mm, respectively. The disadvantages include the difficulty of cutting and processing it - almost special tools are required, a lot of dust is generated. The second disadvantage is related to weight - spend installation of DSP It’s impossible to do it alone.”

Pavel, Nizhny Novgorod.

“When building the house, I used 24 mm thick CBPB as permanent formwork for the foundation. The result was a big saving on scaffolding; when pouring concrete, they did not sag. Subsequently, I covered them with tiles; with minimal glue consumption, they hold up well. I advise you to buy in bulk, at retail the cost of the sheet is at least 10% higher, and the leftovers on the farm will come in handy.”

Igor, St. Petersburg.

"At major renovation At home, I used DSP boards instead of plasterboard for the installation of internal partitions and subflooring. I was surprised by their quality; the end result was perfectly smooth walls. I only puttyed the seams and chose wallpaper for finishing. The disadvantages include the weight and difficulty of processing at home; due to the dust, the cutting had to be done outside.”

Vadim, Moscow.

“I insulated the façade of the house with mineral wool and decided to buy cement-bonded particle boards for the exterior finishing. Difficulties arose only when choosing material for the frame; in the end I settled on wooden beams. There were no problems with the fasteners; under the influence of moisture and sunlight in the summer, the DSP does not behave and does not melt. It’s worth paying attention to the seams, as they explained to me at the hardware store; when cladding facades, they should not exceed 5-8 mm and must be sealed with special mastic.”
