In private housing construction, the choice between wood and stone is the most fundamental question before starting work. Both materials have their pros and cons. What happens if you combine the beneficial properties of cement and wood in one material? The result will be CSP (cement particle board). This is what we will talk about in this article: we will try to understand what types there are and how easier it is to choose a DSP.

Features of cement bonded particle boards

The material is a symbiosis of wood and cement. Unlike other particle boards, it does not contain any synthetic resins; the main binding component is cement. Cement with strength grade M500 is used. Wood chips are sorted into fractions and stabilized. Also added to the product chemicals(aluminum sulfate, sodium silicate), which prevent the process of rotting wood ingredients and eliminate Negative influence chip component for cement. All ingredients are mixed with the addition of water in an industrial mixer. The products are then formed and pressed dry using compressed air.

Compared to other wood-based boards, DSP has a number of features.

• Environmental friendliness- the material does not contain any synthetic resins that are found in chipboard, OSB or fiberboard. Therefore, those who are concerned about the formaldehyde content in composite products should pay attention to DSP.
• High stability- cement particle boards have high wear resistance and moisture resistance. They absorb moisture less than other wood-composite products, while maintaining their overall shape - they do not swell.
• Strength allows the use of CBPB as a structural material; cement boards are superior to other composite analogues, such as fiberboard and OSB (oriented strand board).

Frame house with DSP walls

Oriented strand board is a composite material consisting of large pieces of wood chips that are arranged in layers and pressed into monolithic slabs. The binding element is formaldehyde resins. Products are sensitive to moisture and are easily deformed under its influence. can be an excellent alternative to OSB in the construction of frame houses.

• Fire safety- another plus of the DSP is that the boards do not contain resins or glue, which, when exposed to fire, will burn and generate a large amount of smoke. Portland cement, which is most often used for production, does not support the combustion process. According to the class, the material belongs to low-flammable substances (G1).
• Biological stability- cement is not a favorable environment for the proliferation of fungi and insects, therefore this scourge, characteristic of some types of wooden houses, bypasses houses made of fiberboard.
• Good adhesion to finishing materials- cement particle board lends itself well to finishing and plastering. The sheets have good adhesion to the applied finish.

Speaking about the advantages, one cannot fail to mention the disadvantages cement slabs. Often the choice is in favor of frame construction They do this because DSP is more expensive. Another significant disadvantage is heavy weight. It is difficult to work alone when producing finishing work with cement-bonded particle board products. Also, significant weight makes it difficult to transport products. Cutting causes certain difficulties, since during this process a large amount of cement dust is released.

Physical and technical characteristics

According to state standards is divided into two brands depending on the quality of the products. At the same time, the main physical and technical parameters do not differ. According to GOST, the density of both brands should be 1100 - 1400 kg/m3. According to the standard, several standard sizes are allowed. The lengths are 3200 and 3600 mm, the widths are 1200 and 1250 mm. Production of other sizes is allowed by agreement with the end user.

Another important parameter is moisture resistance. It consists of basic humidity and moisture absorption, i.e. the amount of water relative to the total volume that the product can absorb. The basic humidity for both brands of product should be from 6 to 12%. According to standards, moisture absorption should be no more than 16%, while the change in thickness (swelling) cannot exceed 1.5%, while for some types of wood-based panels this figure can exceed 20%.

Now we need to move from general points to differences.

• TsSP-1- have more flat surface, for this brand, deviations from the plane of the slab are allowed by only 0.8 mm, oil stains and chipped edges are not allowed. There may be no more than one dent up to 1 mm deep on the surface. The permissible bending strength depends on the thickness of the sheet and cannot be less than 12 MPa for 12 mm thick CBPB; for sheets over 19 mm, the permissible bending strength is 9 MPa.
• TsSP-2 designed for lower bending strength. For a 12 mm slab this figure should be at least 9 MPa, for a slab over 19 mm - 7 MPa. This brand also has more defects. For example, there may be oil and rust stains on the surface, and there may be dents more than 2 mm deep on the surface (the maximum allowable quantity is 3 pieces).

Some materials are often called varieties, although they are not such. It’s just that these products are very similar in production method, structure and properties.

Fibrolite- cement-fiber material, long wood fiber is used in production to form boards. Fiberboard has low thermal conductivity, fire resistance and is used for insulation. DSP significantly exceeds it in density and strength.

Arbolit It is made from a mixture of shavings, sawdust and wood chips with cement. The material is used not only as thermal insulation, but also for the construction of walls and partitions. Arbolite is produced in the form of blocks, slabs or floors.

Walls made of arbolite slabs retain heat well due to their low thermal conductivity

Xylolite It is made on the basis of shavings and lightweight concrete. The main scope of application is self-leveling seamless floors and partitions.

Selection based on application

It is used as a heat-insulating, finishing and structural material, so the scope of application is quite wide.

• Construction of a frame house- cement slabs are used for the construction of frame houses. In this role, they replace cheaper, but less moisture-resistant, oriented strand boards. DSPs are used to impart rigidity to the frame and create the structural strength of the house. The distance between the posts should be no more than 60 cm. The slabs allow you to form a “pie” of a frame house, which consists of several layers of sheathing, posts, thermal insulation, vapor barrier and wind protection. The outside of the house is covered with siding or plastered. For walls, sheets with a thickness of 12 - 18 mm are usually used.

Sheathing the house frame with cement-bonded particle boards

• Rough wall finishing- in this case, products made from cement and shavings are used to level the surface wall covering. The material is well suited for subsequent painting or wallpapering. In this case, it is better to choose first-class products, with finishing methods when outer side sheets will be covered with other material, products of the TsSP-2 brand are used.

Wall finished with DSP sheets

• Roofing - cement bonded products are used to create a base for soft roof. The sheets are laid on the sheathing or rafter system. In this case, the thickness of the sheets should be selected based on the pitch of the rafters. Most often, sheets with a thickness of 16 to 24 mm are used.
• Subfloors can also be made using cement bonded particle boards, they provide heat and sound insulation. Installation is carried out on logs or concrete screed. This coating most often serves to level the surface before laying the finished floor. The appearance of the material does not play a special role, since it will be hidden under the laminate or parquet, so you can use the TsSP-2 brand. In this case, it is important to choose the right sheet thickness, which when installed directly on concrete can be 18 - 20 mm. When installing the log system, it is affected by the distance between the bars. For gaps of 60 cm, it is optimal to use slabs of 20 - 26 mm.

Laying a subfloor on a joist system

has high moisture resistance and can remain in the ground for a long time; this property is used to create temporary floors directly on the ground. Such coverings are used for placing building materials and for temporary buildings.

• Internal partitions allow to differentiate inner space in the house into rooms. Due to its good moisture resistance, the material can be used to divide a combined bathroom into two rooms (bathroom and toilet). If painting is planned as a finish, then it is better to choose a grade of material with the least amount of external defects (TsSP-1).

The partition has a complex structure, the frame is made of galvanized profile, mineral wool is used as insulation and heat insulator. DSP acts as an element that gives the structure the necessary strength

• Permanent formwork- for pouring foundations or other architectural forms CSP can be used with concrete, they have good wear resistance and tolerate high humidity, while the products are not deformed, so they are not removed when the concrete hardens and perform a form-building function for various structural elements. For example, cement bonded particle boards are suitable for creating columns. Compared to the use of other wood boards (plywood, OSB), the material practically does not change its geometry and does not swell.

Formwork made of cement bonded particle boards

• Window sills can also be made from small cement particle boards. For this, you can use slabs more than 10 cm thick.
• Door trim- due to its moisture-resistant properties, the material can be used for finishing external doors. For example, cement-bonded particle board products are used to improve sound and thermal insulation balcony doors. In addition, the material can significantly increase the fire-resistant properties of the structure.
• Arrangement summer cottage - DSP is used for the construction of fences and fences. The material does not deform from contact with the ground, so it can be used to create beds. Cement slabs are also suitable for the construction of utility rooms for storing tools and gardening equipment.

DSP: classification, selection and scope of application

The DSP board, the technical characteristics of 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 a 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. The 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. The products are able to provide internal protection from the 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: reduction of the duration of the construction work, reducing 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.

When performing construction and finishing work, the most important aspect is the reliability and durability of the resulting structure, but not all materials provide such parameters. That is why great solution is a cement-bonded particle board that has the necessary performance characteristics. Products have their own characteristics that should be taken into account to achieve best result.

Explanation: CSP – cement particle board. The products include the following components:

• High grade Portland cement (from M400) – 65%.
• Wood shavings (most often coniferous) - at least 24% of the total mass.
• Water without impurities – 8.5%.
• Special mineral additives (sodium silicate, aluminum sulfate and others) – 2.5%.

The availability of the components of cement bonded particle boards determines their high popularity

The products belong to composite materials and have been known for quite some time, which is confirmed by GOST 26816-86. For a long time it was unclaimed due to the wide diversity of the construction market.

At the moment, the production of the material is regulated by GOST 26816-2016. This standard is based on a 1986 document and European standards EN 634-1:1995 and EN 634-2:2007. Although the demand for products is increasing, due to their excellent qualities and reasonable prices, their availability remains quite low.

Production of material

The plate manufacturing technology includes a number of successive stages:

Modern production is constantly developing, so it is possible to obtain CBPB sheets with minimum thickness 6 mm without loss of properties.

Advantages and disadvantages

The material stands out from the rest with many advantages:

But the DSP board also has disadvantages:

When purchasing, pay attention to the presence of safety certificates.

Types of cement bonded particle boards

The panels have a similar composition and allow you to choose suitable material for a specific situation:

The characteristics of xylolite and fibrolite are very different, therefore their purposes are different

• Xylolite. The base contains shavings and magnesium cement. It has high strength, so it can be used as a floor covering.
• Fibrolite. For production, wood raw materials that have undergone special processing and burnt magnesite are used. Portland cement is used as a binding component. The resulting parts are soft and suitable for thermal insulation.
• Arbolit. Quite a popular variety for exterior and interior work.

The use of new technologies allowed Arbolit to become a sales leader

Also, parts are usually divided according to their area of ​​use, depending on their thickness. There are two brands of products: TsSP-1 and TsSP-2, which differ in parameters.

Specifications

Such facing material has the following properties:

1. Flexural strength. From 9 to 12 MPa. This indicator indicates that the installation site should be level. But the panels have high resistance to longitudinal deformation, which makes it possible to use them to strengthen load-bearing structures.
2. Density. From 1200 to 1400 kg/m3. Values ​​vary due to possible humidity fluctuations.
3. Vapor permeability. It is about 0.03 mg/(m h Pa). The presence of a porous structure does not prevent vapor exchange.
4. Humidity level. Within 9%. If the manufacturing technology is fully followed, then with constant exposure to water during the day, the indicator changes by less than 2 times.
5. Thermal conductivity. Coefficient – ​​0.26 W/(m K). If you cover a house with such material, its energy efficiency will increase.

Sheet size:

• width – 120 and 125 cm (standard);
• length – 320 and 360 cm;
• thickness – from 6 to 36 mm;
• the weight is determined by the dimensions: a panel 1200*3200*36 will have a mass of 195 kg.

There are other options, regulations allow the production of parts required sizes.

Design parameters of the best-selling DSP models

Since the material is environmentally friendly and moisture-resistant, the area where it can be used is quite extensive:

1. Frame construction. In such a situation, dimensional parts should be used, because they enhance bearing structures. Wall ceilings are completely sheathed with slabs, the field of which is processed.
2. Facade finishing. This is the most the best option, if the climate of the area is with high humidity and severe frosts. Panels are used when constructing a system with additional ventilation: they are laid on the lathing. Due to the fact that the products can be sanded or unpolished, they are left without facing or plastered.
3. Interior work. Slabs are used to cover walls and ceilings. In larger-scale processes, the material is used to furnish the attic and subfloor.

Renowned brands such as Tamak produce a complete line of high quality cement boards for different types finishing and operation

The characteristics make it possible to use cement chip panels almost anywhere, if practical. Although all the work can be done with your own hands, the size and weight of the parts require the presence of an assistant.

Cement particle board (CPB) 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. In process creation of DSP The following steps are included:

• 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;
• at the 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;
• weight of one square meter DSP having a thickness of 8 mm reaches 10 kg.

The material has 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 effect 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 rich 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 DSP can be classified as:

• 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. The risk of breakdown 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.

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, which can be used as finished goods 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 from the outside and inner sides walls at the same time. If you want to insulate a utility room, then it is permissible to leave a 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 completing all stages can you carry out external finishing floor covering.

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.

In the modern building materials market, various sheet finishing materials are presented in a wide range. This is chipboard and OSB boards, various types of plywood, drywall and other modifications. Despite this, the DSP board, the use of which is not limited only to interior work, deserves special consideration.

The unique structure of the material, which consists of seemingly incompatible ingredients, provides DSP with characteristics that are not only not inferior to analogues, but also superior to them in some respects. Relatively low cost, strength and reliability, weather resistance and ease of installation make the material indispensable for any construction and repair work.

In most cases, for the installation of DSP boards, the use of a wooden or metal frame is necessary, so it is worth stocking up in advance necessary material and fasteners.

What is a DSP board?

Wood chips and cement are used to produce this unique building material. The wooden filler is pre-crushed and sorted, after which it is antiseptically treated with calcium and aluminum chlorides. The components are thoroughly mixed, and the resulting mass is poured into special molds. As a rule, the composition of a cement-bonded particle board (CSB) includes:

• Portland cement - 65%;
• Wood shavings - 24%;
• Water - from 8.5 to 9%;
• Hydration and mineral supplements - from 2 to 2.5%.

To reduce internal stresses and more efficient pressing, a small amount of fuel oil or industrial oil can be added to the prepared mixture. The filled forms are stacked and pressed. Operating pressure can vary from 1.7 to 6.5 MPa. To accelerate hydration and hardening of the mixture, it is subjected to intense heating for 8 hours.

Important!

The elasticity of wood chips compensates for the shrinkage of cement, therefore, even during the drying process, the dimensions of the slabs remain unchanged.

After removal from the formwork, the CBPB board is transported to the technological warehouse, where it finally dries in natural conditions. The final stage of production is hot air blowing, cutting, polishing and delivery to the storage location.

DSP board: technical characteristics

Before using the material, it is necessary to study its basic operational and technical characteristics. Currently, according to GOST 26816-2016, the domestic industry produces two types of CBPB boards, the characteristics of which are given in the table:

Options	TsSP-1	TsSP-2
Bending elasticity index, MPa
Surface hardness, MPa
Thermal conductivity of the material, W/(m °C)

Scope of application of CBPB boards

As mentioned above, CBPB boards, the use of which provides high mechanical strength created structures are widely used in construction, repair and finishing works, 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 effective 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 make it possible to create various types of ventilated facades. As for the sheet thickness, for outdoor use it can vary from 12 to 14 mm.

DSP board: sizes and prices

Regardless of the brand, TsSP-1 or TsSP-2 (GOST 26816-2016), the sheet size can be:

• Thickness: 8-40 mm, in 2 mm increments;
• Length: 2700/3200/3600 mm;
• Width: 1200/1250 mm;

Depending on the thickness and overall dimensions The weight of the sheet can vary significantly:

Overall size, mm	Weight, kg

The table shows that the DSP sheets large thickness They have a significant mass, therefore, when working with them, it is advisable to use various lifting devices.

Methods of fastening DSP panels

Depending on the thickness of the DSP sheet and the type of work performed, the fastening can be:

• With open seam on screws;
• With open seam on nails;
• WITH closed seam on screws;
• With closed seam on nails;
• Using aluminum profile;
• Using a decorative strip.

The last two methods are most often used for decorative processing of facades.

Types of DSP: characteristics and their application

Depending on the structure of the wood filler, features and, a number of modifications have been developed based on DSP:

Fibrolite . Thin long shavings of coniferous species are used as a binding element. The mechanical properties of the filler contribute to an increase in fiberization rates, which significantly increases the strength and elasticity of the material. The surface hardness of the semi-finished product is slightly less than that of CBPB. As a rule, fiberboard serves as good sound insulation.

A rbo lit . Wood processing industry waste, dry reeds and even cereal straw are used as filler. Despite the fact that the manufacturing technology remains unchanged, the strength is noticeably lower than that of CBPB. The main area of ​​application of the material is cladding load-bearing frames internal partitions, heat and sound insulation.

Xylolite . Sorel cement provides high resistance to moisture and water. Thanks to this, the material has become widespread in façade cladding. Laying rough floors and installing roofing coverings.

How to prime DSP

Before you start final finishing surfaces made of CSP boards, it must be treated with a primer, preferably deep penetration. For interior work, you can use the time-tested primer Ceresit ST 17, but its cost is quite high. There are other deep penetration acrylic compositions that are not much inferior to CT 17 in quality, and their cost is noticeably lower.

You can make a primer yourself by carefully dissolving 1 kg of PVA glue in 10 liters of water. This mixture is significantly inferior to deep penetration primers, but still better than nothing.

For processing facade cladding from DSP, the use of a special primer is mandatory, otherwise the painting will end in disaster very soon. As a primer, you can use a 10% solution of acrylic facade paint.

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 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 also water-soluble facade paints acrylic paints, at correct application, 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. Painting works You can do it yourself, which will save you a significant amount.

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

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

Advantages and disadvantages of using CBPB

Like any material, DSP, despite its undeniable advantages, also has some disadvantages; let’s take a closer look at the pros and cons of DSP panels, the characteristics of which were given above. The advantages of the material include the following properties:

• High strength;
• DSP sheets, even with a small thickness, provide a high degree of sound insulation;
• Cement particle board does not burn even at very high temperatures;
• Even without additional processing, it has antiseptic characteristics;
• Vapor permeability;
• Water resistance.

The disadvantages of the material are less significant:

• Big specific gravity slabs that complicate installation work;
• Insufficient strength under bending loads;
• Difficulty in cutting and increased and large amounts of dust when cutting with power tools;

In order to draw final conclusions, it will be useful to study reviews on the Internet; here are some of them.

Cement particle board: consumer reviews

Positive reviews confirm the above advantages of the material:

1. I decided to use DSP boards for the flooring. On crushed stone cushion laid a slab 26mm thick. After that, I laid down waterproofing and mineral wool, and attached the joists. The subfloor was laid with 16 mm slabs, on top - regular linoleum. I am very pleased with the result, dry and warm. Nikolay, Stavropol region.
2. Family circumstances forced us to establish interior partition. The drywall seemed not strong enough, so I decided to use 8 mm DSP. Installation on a 50x50 mm wooden frame did not take much time, and cutting was not very tiring. All that's left is to putty and wallpaper. The design turned out to be durable and reliable, I’m very pleased good material. Andrey. Kharkiv.

In negative reviews, the most complaints are about the heavy weight of the material and other difficulties during the installation process:

I have been involved in construction and finishing for 15 years. The last object can be considered a year or two! The fact is that the customer decided to use 16 mm DSP instead of plasterboard for internal partitions, and decided to cover the facade with it. We didn’t have any lift; we fixed it manually. Perhaps the material will justify itself, but it is very difficult to install. Victor. Ryazan.

As soon as I started cutting the DSP for the partition I immediately realized what I had done terrible mistake. I cut it with a grinder with a diamond blade, there was no dust except in the next block! There is no longer any desire to cut DSP panels indoors. Alexei. Novosibirsk

In the case of facade cladding, there are practically no negative reviews:

The outside of the house is covered with DSP panels and painted, with a layer of polyethylene and mineral wool laid underneath. The house has been dry and warm for two years, there are no fly agarics, cracks or mold outside, we are very happy. Karina. Volgograd region.

Cladding the garage with DSP slabs did not cause me any difficulties. I used the 12 mm version and a wooden frame made of pine beams 50x50 mm. I watched horror stories about possible cracks due to thermal expansion and decided to leave decorative seams, well, it seems like that’s what was intended. Painted it facade paint And now for the third year there are no problems. Yuri. Smolensk region.

Having carefully analyzed the performance properties of DSP panels and consumer reviews, the following conclusions can be drawn:

• The material is quite budget-friendly;
• The price/quality ratio is acceptable;
• Simple installation technology allows for independent installation;
• Inconveniences during installation are due to the high specific gravity of the material;
• When cutting there is high dust content.

In general, DSP boards are in demand for both interior, exterior and landscape work.
