In contrast to magnesia concrete, polymer-cement concrete has full resistance to water.

Polymer concrete

Other names: cement-polymer concrete, cement polymer concrete.

As mentioned above, polymer-cement floors based on Elastobeton-B concrete additive are 20-50% cheaper than magnesia floors. But this is a direct calculation - that is, they took polymer-cement concrete - they calculated the price of the components; similarly for magnesia concrete.
But besides this, there are a number of factors that affect the final price of polymer-cement concrete and magnesia concrete. The main of these factors are listed below.

1. Transportation.
The transport of concrete components has a very strong impact on its final cost.
If the transport costs are only RUB 1 / kg, then delivery main components magnesia concrete, which make up about 23% of the total mass, will increase the price of 1 m³ of concrete by 500 rubles! With a delivery price of 5 rubles / kg, this is already 2500 rubles / m³!

If all the components of magnesia floors are transported, then with a delivery price of 1 RUB / kg, the price will rise to 2,200 RUB / m³.
With a delivery price of 5 rubles / kg, magnesia floors will become more expensive by 11,000 rubles / m³!

Additive for concrete Elastobeton-B is about 3.5% of the concrete mass, the rest of the components you purchase on the spot. Accordingly, the transportation of polymer additives for concrete, even over long distances, practically does not affect the price of polymer-cement concrete.

The savings are clear.

2. Storage.
The components of magnesia concrete (in particular burnt magnesia - magnesium oxide) are very sensitive to storage and transportation conditions. Penetration, ingress of moisture into the components significantly reduces the final strength of magnesia concrete. As a result, you will receive magnesia floors with the brand strength M200-M300, instead of M400-M600.

There are no such problems with polymer-cement concrete, since you buy all the components of the feed additives on the spot and you can always check their quality.

3. Cost of fillers.
The cost of concrete with the addition of "Elastobeton-B" depends on the modulus of sand size (MCR), bulk density of sand and bulk density of crushed stone. The higher the FIBC and the higher the density of sand and crushed stone, the less cement and concrete admixtures in relation to sand and crushed stone. Accordingly, the cheaper is polymer-cement concrete.

Savings can be up to 2,000 rubles. per 1m³ of polymer-cement concrete.

4. Corrosion of equipment.
Magnesia concrete will include a bischofite component that causes increased corrosion on both steel and aluminum surfaces of equipment. Equipment (concrete mixers, vibrating screeds, helicopters, etc.) must be constantly washed. But even with careful maintenance, the service life of the equipment is reduced by several times, which, as a result, is reflected in the price of magnesia floors!

Polymer additive for concrete Elastobeton-B does not have a corrosive effect on metal surfaces.

The savings are clear.

Polymer additive for concrete - properties, advantages

Elakor "Elastobeton-B"- complex modifying polymer additive for concretes (Portland cement concretes).
For use, cement of the M500D0 brand is recommended. If you want to use other cements, we recommend that you first check them for compatibility with the Additive (see Additive Application Technology). The fact is that some of the fillers that are introduced in the manufacture of cement can "conflict" with the additive.

To make colored polymer-cement floors, you can add the pigment yourself directly when mixing concrete or order the Additive of the desired color from us.
Colored polymer-cement floors can be made on gray cement, but if a "pure" color is required, then white cement must be used.

Polymer-cement floors are used at facilities.

Polymer concrete is a special building material that is used as a bonding element and also to replace lime cements. In some cases, the polymer is used as an adjunct to Portland cement. It is a versatile, durable composite made by mixing various mineral fillers with synthetic or natural binders. This advanced technical material is used in many industries, but the most common in the construction industry.

Views

Three types of polymer concrete are used in construction. Next, we will take a closer look at their manufacturing technology, field of application and compositions in order to have a general idea of ​​polymer concretes and their modifications.

Polymer compositions for concrete (polymer modified concrete)

This type of concrete is made from a Portland cement material with modified polymer such as acrylic, polyvinyl acetate and ethylene vinyl acetate. It has good adhesion, high flexural strength and low permeability.

Acrylic polymer modified concrete is characterized by a long-lasting color, which is why it is in great demand among builders and architects. Its chemical modification is similar to the traditional cement variation. The amount of polymer is usually 10 to 20%. Concrete modified in this way has a lower degree of permeability and a higher density than pure cement. However, its structural integrity is highly dependent on the Portland cement binder.

Concrete may take longer to degrade if it has a high density and less surface area. A relative improvement in the chemical resistance of the polymer-modified material to Portland cement is possible in an acidic environment.

Resin impregnated concrete

Polymer impregnation for concrete is usually done by incorporating a low density monomer into hydrated Portland cement, followed by radiation or thermal catalytic polymerization. The modular elasticity of this type of concrete is 50-100% higher than that of conventional concrete.

However, the modulus of the polymer is 10% greater than that of normal concrete. Due to these excellent characteristics, among the many applications for polymer building materials, the production of:

  • decks;
  • bridges;
  • pipes;
  • floor tiles;
  • construction laminate.

The technology of the embedding process includes drying concrete to remove moisture from its surface, using monomers in a thin layer of sand, and then polymerizing the monomers using a heat flux. Consequently, concrete surfaces have lower water permeability, absorption, abrasion resistance, and generally high strength. Also, to increase wear resistance, resistance to cold and moisture, polymer bricks, stones, floors, etc. are used.

Polymer concrete

It has nothing to do with the usual Portland cement for us. Formed by combining stones with a polymer binder that does not contain water. Polystyrene, acrylic and epoxy resins are monomers that are widely used in the manufacture of this type of concrete. Sulfur is also considered a polymer. Sulfur concrete is used for buildings requiring high resistance to acidic environments. Thermoplastic polymers, but most often thermosetting resins, are used as the main polymer component because of their high thermal stability and resistance to a wide range of chemicals.

Polymer concrete is made up of aggregates that include silica, quartz, granite, limestone and other high quality materials. The unit must be of good quality, free from dust, debris and excess moisture. Failure to meet these criteria can reduce the bond strength between the polymer binder and the aggregate.

Features of polymer concrete

The modern building material is different from its predecessors. It has the following characteristics:

  • High resistance to chemical and biological media.
  • Compared to cement-concrete products, it has a lower weight.
  • Excellent noise and vibration absorption.
  • Good weathering and UV resistance.
  • Water absorption.
  • Can be cut with drills and grinders.
  • Can be recycled as crushed stone or crushed for use as a road base.
  • About 4 times stronger than cement concrete.
  • Good thermal insulation properties and stability.
  • Ultra-smooth finish that promotes efficient hydraulic flow.

Usage

Polymer concrete can be used for new construction or renovation of old material. Its adhesion properties allow the restoration of both polymer and conventional cement-based concretes. Its low permeability and corrosion resistance make it suitable for use in swimming pools, sewerage systems, drainage channels, electrolytic cells and other structures containing liquids or harsh chemicals. It is suitable for the construction and rehabilitation of wells due to its ability to withstand toxic and corrosive sewer gases and bacteria commonly found in plumbing systems.

Unlike traditional concrete structures, it does not require coating or welding of protected PVC seams. You can see the use of polymer concrete on the streets of the city. It is used in the construction of road barriers, sidewalks, drainage ditches, fountains. Also on the street for concrete, they are added to asphalt during the construction of open areas, runways and other objects that are in the open air and are constantly exposed to external atmospheric influences.

Polymer concrete is one of the most recent inventions given to us by process engineers. The peculiarity of this building material is that it contains various polymer additives. Typical components of such concrete are styrene, polyamide resins, vinyl chloride, various latexes and other substances.

The use of admixtures allows you to change the structure and properties of the concrete mix, improve its technical performance. Due to its versatility and ease of production, polymer concrete is used almost everywhere in our time.

Views

There are two types of polymer concretes, each of which is used for certain types of construction work. The first option is filled polymer concrete. The structure of this material contains organic compounds that fill the voids between the filler (crushed stone, gravel, quartz sand).

The second option is molecular frame concrete. The voids between the fillers remain unfilled, and the polymeric materials are needed to hold the particles together.

Polymer concrete is a concrete in which the mineral binder in the form of cement and silicate is replaced in whole or in part by polymer components. The types are as follows:

  • polymer - a polymer added to concrete makes up 5-15% of the mass of cement (phenol-formaldehyde resins, polyvinyl acetate, synthetic rubber, acrylic compounds). Very durable against liquids, shock and are used for the construction of airfields, brick and concrete finishing, ceramic and glass, stone slabs;
  • plastic concrete - thermosetting polymers (epoxy, phenol-formaldehyde and polyester) are used in the mixture instead of cement, the main property of such concrete is high resistance to acids and alkalis and instability to temperatures and deformations. They are used to cover structures in protection against chemical aggression and to repair stone and concrete elements;
  • concrete polymer is concrete impregnated after hardening with monomers, which fill the pores and defects of concrete, which results in strength, frost resistance, wear resistance.

Advantages and disadvantages

Why has polymer concrete become a worthy competitor to traditional building materials? It hardens quickly and becomes as strong as granite. The curing time is significantly shorter than that for conventional concrete.

The polymer component gives its maximum tensile strength to concrete a week after pouring. Ordinary concrete takes about a month to do this.

Concrete contains agricultural and construction waste. Previously, they were not processed in any way and in most cases they were simply buried in the ground. The use of waste in the preparation of polymer concrete solves the issue of processing and significantly reduces the negative impact on the environment.

Since these same wastes are widespread almost everywhere, there is already a good raw material base for the production of polymer concrete. No special additives and impurities usually need to be purchased. The technology for making such concrete is available even for novice builders. In the process of preparing a concrete mixture, everyone himself can experiment with the amount of additives and impurities, but the initial list of components remains unchanged.

The disadvantages of polymer concrete include a significant proportion of its artificial components. The mixture contains about 10% of substances of artificial origin. The second drawback is the lack of standardization in accordance with GOST. You cannot be sure that the concrete you need is on sale. The third disadvantage is the high cost due to the cost of additives (resins, etc.).

Composition

One of the most important components of polymer concrete is fly ash. This substance is a product of coal combustion. The use of ash as an additive has a filling effect on the fresh concrete mix. The filling effect is based on the ability of the smallest coal particles to fill all voids and porous formations. The smaller the ash particles are, the more fully this effect is observed. Thanks to this feature of fly ash, the cured concrete becomes much stronger and stronger than usual.

Another important component of the concrete mix is ​​water glass. It has excellent adhesion and low cost. Its addition to polymer concrete will be very useful if the finished structure will be outdoors or exposed to constant exposure to water.

The technical characteristics of polymeric concrete are higher than those of other standard concrete and, moreover, it is environmentally friendly - it can be used in the construction of buildings in the food industry. The averages are as follows:

  • linear shrinkage 0.2-1.5%;
  • porosity - 1-2%;
  • compressive strength - 20-100 MPa;
  • heat resistance - 100-180С;
  • creep measure - 0.3-0.5 kg / cm2;
  • aging resistance - 4-6 points.

This type of mixture is used as a structural and decorative finishing material.

Self-manufacturing technology

If you have the necessary knowledge and appropriate materials, you can make polymer concrete with your own hands. But it should be borne in mind that there is no specific recipe for the preparation of such concrete, the balance of the components is determined based on practical experiments.

The very technology for preparing polymer concrete is quite simple. The concrete mixer is filled with water and a small amount of cement. Then slag and fly ash are added in equal amounts. All components are thoroughly mixed. Next comes the turn of various polymer components. They are added to the previous ingredients, after which the mixture must be mixed again.

Liquid glass, PVA glue, various water-soluble resins are suitable as a polymer additive. PVA glue can be used in any quantity, as it is an excellent filler with good viscosity. Its addition to the concrete solution significantly improves the durability parameters of the finished structure, and reduces the percentage of shrinkage.
The ratio between polymers and binders can be from 5: 1 to 12: 1.

Application

The most rational is the use of polymer concretes as decorative and protective products made of concrete or metal. It is advisable to carry out one or another design entirely only in some cases. Usually this is the manufacture of electrolysis or pickling baths, pipelines or containers for corrosive liquids. The manufacture of building or enclosing structures from this material does not seem to be either expedient or economically viable.

Polymer concrete is highly resistant to external influences, so it can be installed without additional reinforcement. But if there is still a need for an additional margin of safety, then fiberglass or steel is used to reinforce polymer concrete. Other elements, such as carbon fiber, for example, are used much less frequently.

The technical capabilities of polymer concrete make it a convenient and inexpensive material for the manufacture of decorative building elements. To obtain various colors, dyes are added to the ready-made solutions, and to give the desired dimensions, they are poured into specially prepared forms. The resulting products from polymer concrete are very similar in color and texture to marble, but the cost of such structures is much lower.

Polymer concrete (also called cast or artificial stone, polymer cement, concrete polymer and plastic concrete) is an alternative type of concrete mix that uses a polymer (synthetic resin) instead of the standard binder. Thanks to this component and cheaper mineral fillers, the composition is distinguished by high moisture and frost resistance, but at the same time the price of a cast stone is lower. Let's take a closer look: polymer concrete - what is it and is this material really worth using in construction, as a replacement for the usual concrete?

To answer this question, first of all, we will determine which components the plastic concrete includes.

Composition of polymer concrete

Aggregate takes the lion's share of the polymer cement composition and it is added of two types at once:

  • Ground - talc, graphite powder, andesite flour, ground basalt, mica and other raw materials.
  • Coarse - gravel, crushed stone, quartz sand.

Important! In the production of cast stone, metal dust, cement lime and chalk must not be used.

Resin is used as a "bonding" component:

  • furan-epoxy (must meet the requirements of TU 59-02-039.13-78);
  • furfural acetone (FAM), meeting the standards TU 6-05-1618-73;
  • urea-formaldehyde (complies with GOST 14231-78);

Polyester resin is often used to hold the core together as it is cheaper than others. It is also allowed to use methyl methacrylate monomer (methyl ester) that meets the standards of GOST 16505.

In addition, the cast stone contains hardeners, plasticizing additives and coloring components. They must also comply with the requirements for chemical additives (GOST 24211).

Depending on a particular quantity and type of components, polymer concrete of different quality can be obtained.

Varieties of polymer concrete

Depending on what kind of filler (or rather its fraction) you added to the cast stone solution, you can get material both for creating light decorative elements and for building more massive structures.

Based on this, the following classes of polymer concrete are distinguished:

  1. Super heavy. The density of such concrete ranges from 2.5 to 4 t / m 3. Components with a size of at least 2-4 cm are used as an aggregate for a super-heavy building material. This type of concrete is used for the construction of structures that are subject to great pressure (load-bearing structures, foundations).
  2. Heavy (density from 1.8 to 2.5 t / m 3). Such structural type plastic concrete is suitable for the manufacture of decorative cast stones imitating marble and other expensive stones. The size of the aggregate for heavy polymer concrete should not exceed 2 cm.
  3. Light. Since the density of such a material is 0.5-1.8 t / m 3, it is usually referred to as concrete of a structural and heat-insulating class. This type of concrete polymer is distinguished by high rates of heat conservation. The aggregate for its preparation is used in the same fraction as for heavy polymer concrete, only its amount changes.
  4. Ultralight. The density of such a composition is from 0.3 to 0.5 t / m 3, therefore it is used for thermal insulation work and for the construction of internal partitions. As a filler, various shavings, perlite, cork and polystyrene with a fraction of no more than 1 cm are most often used.

Healthy! Most often, polymer concrete is used for the manufacture of: kitchen countertops, sinks, window sills, columns, steps, monuments, fireplaces, fountains, floors, vases and much more.

There is also the lightest artificial stone, with a filler size of no more than 0.15 mm. This material has found application in the production of decorative elements.

Polymer concrete properties

If we compare the concrete polymer with ordinary concrete, then it is worth noting the fact that, in many of its characteristics, the composition with the addition of resins bypasses the usual mixtures. Polymer concrete has the following properties:

  • density - 300-3000 kg / m 3;
  • compression resistance - from 50 to 110 MPa;
  • bending resistance - from 3 to 11 MPa;
  • abrasion in the range of 0.02-0.03 g / cm 2;
  • temperature limit - from 60 to 140 0 С;
  • elasticity - from 10,000 to 40,000 MPa;
  • thermal conductivity coefficient - 0.05-0.85 W / m · K;
  • moisture absorption volume - 0.05-0.5%;

Strength characteristics of polymer concrete are 3-6 times higher than those of ordinary concrete. The same applies to the tensile strength, which is almost 10 times higher for a concrete polymer.

It is also worth considering the chemical passivity of the modern concrete composition, which is determined in accordance with GOST 25246-82. It follows from this regulatory document that at 200 0 C Celsius, the chemical resistance of the concrete polymer components to nitric acid will be at least 0.5%, and to hydrochloric acid, ammonia or calcium solution at least 0.8%.

Based on this, we can conclude that polymer concrete, which contains resins, has all the qualities necessary for the construction of various objects.

Advantages and Disadvantages of Casting Stone

Polymer cement is often used in the construction of structures that cannot be made from ordinary concrete due to its fragility. Due to the polymer composition, structures will be less susceptible to deformation or destruction.

In addition, polymer concrete has the following advantages:

  • Due to the high water resistance and resistance of the concrete polymer to temperature extremes, water droplets evaporate almost immediately on the surface of the finished product, as a result of which cracks and other defects do not form.
  • The surface of the polymer cement remains smooth throughout the entire service life, thanks to which polymer concrete products do not get dirty.
  • The variety of colors allows you to create products from this material, stylized as expensive natural rocks (granite, marble and others).
  • The material is recyclable with the possibility of reusing concrete polymer.
  • Structures made of this lightweight concrete do not need additional processing.

If we talk about the shortcomings of modern material, then it is worth highlighting the following disadvantages:

  • Flammability of polymer concrete.
  • The high cost of some binding components (however, if you use ground flour as an aggregate, then costs will be significantly reduced).
  • It is not always possible to find on sale everything necessary for the production of such a composition.

Speaking about the production of polymer concrete, it is worth considering the possible options for the manufacture of such concrete.

Casting stone production methods

The process of making concrete polymer can be continuous or batch.

Continuous production

In this case, we are talking about a large-scale production, for which it will be necessary to purchase the appropriate equipment:

  • Vibrating table.
  • Stirrer.
  • Compressor system with a pistol.
  • Silicone matrices.
  • Extractor hood.
  • Grinding and polishing machines.

To purchase everything you need, you will have to spend about 250,000 rubles. Even if you take into account that you will make some of the equipment on your own, the most expensive tools will have to be purchased. Therefore, we will not dwell on this production method and consider a more accessible technology.

Making polymer cement at home

Knowing what polymer concrete is, it becomes obvious why this material is most often used for the production of countertops and decorative elements for a suburban area. Fortunately, you do not need specialized equipment for its "home" production.

To make polymer cement with your own hands:

  1. Rinse and clean the aggregate. Then dry it until the moisture content of crushed stone or gravel is 0.5-1%. If you use a wet aggregate, the strength of the finished product will decrease.
  2. Sift the sand and remove impurities from it.
  3. Pour crushed stone into the concrete mixer first, then sand and aggregate and mix the components for 2 minutes.
  4. Add water and stir again.
  5. Soften the binder (resin) with a solvent or simply by heating the solid mass.
  6. Add plasticizer, stabilizers and other components to the resin. Mix them separately from the aggregate for 2 minutes.
  7. Add hardener.
  8. Stir all ingredients for at least 3 minutes until you get a creamy mixture.
  9. Pour the resulting mixture into a paraffin waxed matrix or prepared formwork. Try to fill immediately the volume of the composition that completely fills the form. Polymer concrete sets very quickly, so you need to act quickly.
  10. Smooth the surface and compact the mixture on a vibrating table.
  11. Wait a day and remove the finished product from the matrix.

On this, the production of polymer concrete can be considered finished.

The main difference between polymer concrete and other concrete mixtures is the use in the production of organic compounds. Polymer concrete is a mixture of various binders and polyester resins, which are combined with various substances (catalysts, hardeners and solvents). In terms of its physical and mechanical characteristics, polymer concrete is far superior to other types of concrete. It has increased plasticity, increased strength, it is not afraid of water and frost, and is resistant to abrasion. If you wish and have some knowledge of production technology, it will not be difficult to make polymer concrete with your own hands.

Polymeric concrete surpasses all other types of concrete in terms of mechanical and physical characteristics.

Where is this material used?

Due to all its positive characteristics, the applicability of this material in construction is much higher than that of others. This material is used:

  • as an insulating coating for concrete;
  • when laying high-strength bricks;
  • as a weather-resistant painting material;
  • for decorative finishing of facades of premises;
  • for putty and plaster;
  • as an adhesive solution for tiles;
  • covering for warm floors.

Due to its characteristics, such as high plasticity and low porosity, stable strength, which is achieved in a short period of time, polymer concrete can be produced by the vibration molding method. It can also be used to work with products of small forms of architecture, decorative items for furniture and supporting structures.

Transparent concrete: some features

Improvements occur every day, including in the construction sector. Concrete is known to be more durable than light transmitting. This was until the time when a new product appeared on the market - transparent concrete. This material is a mixture of concrete and glass filaments, which allow ordinary cement mortar to take on the increased hardness of the concrete mortar, plus a rather significant transparency.

Thanks to the presence of glass fibers in the concrete, silhouettes can be seen through it.

The technical name for transparent concrete is litracon. It is executed in the form of blocks, not much more than a brick, and because of the transparency it seems completely weightless. This material can rightfully take a place in the range of decorative and building materials. According to manufacturers, such blocks, in addition to being used in the construction of partitions, can even be used for paving sidewalks, since glass fibers make up only 4% of the total part of the concrete solution, and the material retains many of the advantages of a concrete mixture.

Due to the presence of glass fibers in the composition, it is possible to see the silhouette of a person or, for example, a tree through the new material. Blocks made of this material allow you to fill the living space with light, make it light and airy. It seems as if the walls are practically non-existent. It is preferable to use such blocks in rooms that were originally built "deaf", it concerns corridors and storage rooms. If you use LED backlighting when erecting a transparent concrete partition, you can achieve amazing effects.

The sizes of the blocks produced can be different, which does not at all interfere with the transmission of light through them. These blocks transmit solar and electrical rays up to 20 meters. And the production technology can vary depending on the customer's requirements. Glass fibers can be distributed both along the entire perimeter of the block, and concentrated in a certain part of it, and in some cases there is the possibility of forming certain contours.

Printed concrete: basic properties

Printed concrete is widely used for paving sidewalks, pavements, swimming pools, facades and interiors.

In recent years, decorative forms of concrete have become increasingly popular. This technology is widely used for paving sidewalks, swimming pools, pavements, in the interior and on the facades. Colored concrete surfaces are increasingly being used, which is also an innovation in the construction industry. This concrete is produced by imprinting texture on the surface of the concrete, thereby imitating any surface, from stone to tile.

For the production of printed concrete, concrete of the M-300 grade is used using fiber as a reinforcing material. After the concrete is poured into the molds, its surface is imprinted with the molds and, as a final step, is treated with varnish, which prevents moisture from penetrating into the pores of the concrete, and the effect of moisture repelling occurs.

Another name for printed concrete is press concrete, which fully reflects its essence: a matrix with a pattern is imprinted on the surface of the coating, due to which it is possible to create a complete imitation of a stone coating with minimal labor costs. Printed concrete combines the main consumer characteristics - wear resistance and decorative appearance. In addition to a large selection of textures for the production of concrete, it is possible to paint it in various colors.

Printed concrete is superior to asphalt and concrete tiles in many of its technical characteristics. It has increased resistance to aggressive environmental components, as well as an increased temperature limit from + 50 to -50 ° C. Such a coating is easy to clean, it is not slippery, which makes it indispensable when laying the coating in swimming pools. Such concrete does not lose its original color when exposed to ultraviolet rays. Stunning decorative effects can be achieved using printed concrete.

The coating made of this material withstands about 300 freeze and thaw cycles, which makes it the absolute leader among other materials. In addition, such concrete is not subject to destruction under the influence of acids and alkalis, which makes it an excellent material for organizing flooring in garages or auto repair shops.
