The characteristics and composition of the foam blocks
Discover characteristics of foam concrete blocks before their acquisition. This material is considered to be quite safe and breathable facings. Air blocks contain the following components:
- Mixtures with binder composition of the Portland cement type;
- sand mixture with quartz content;
- water corresponding to GOST;
- foaming agent, which may consist of different materials.
Foaming agents can be either synthetic or natural.
The main characteristics of the materials:
- depending on the density of the foam blocks are structural, thermal insulation and structural-thermal insulation;
- thermal conductivity It depends entirely on the further use of the blocks;
- foam is characterized by high frost resistance. The water in the micropores is not converted into ice even at low temperature values;
- foam block may differ according to manufacturing methods. Cut element is cut to specific sizes. Molded block manufactured in special molds.
Most often, this material is purchased for the construction of structures such as buildings carrying, for everything partitionsAs well as soundproofing and creating insulation for floorsThe roof and wall.
Kinds | stamps | Density, kg / m3 | application |
Structurally Porous types | D 1300-1600 | 1300-1600 | Recommended for buildings of different heights. |
construction | D 900-1200 | 900-1200 | They can be used in high-rise building, because have high resistance to compression |
Construction-insulating | D 600-800 | 600-800 | Suitable carriers for the manufacture of the walls. Demand for construction private houses. |
Thermal insulation | D 300-500 | 300-500 | They are used as an insulating layer, as they have a low thermal conductivity levels. |
Advantages of foam blocks
Play an important role in choosing the size of foam blocks and the price per unit, as well as the pros and cons of the product. At the material are the following advantages:
- Compressive strength of the product is determined by the blowing agents, which are in its composition. In determining this important parameter humidity indicator material;
- It depends on the brand of the density of the product. For construction low-rise buildings The applied foam block marks 600-800;
- lightweight material that saves on construction foundation;
- low thermal conductivity index, allowing foam blocks to retain heat for a longer time;
- excellent sound insulation index. The porous structure absorbs high sounds;
- security foam blocks due to their flame-retardant properties;
- reasonable price products. The cost of the foam block per share equal to the average of 50-150 rubles;
- ease of installation works;
- foam allows you to specify the exact dimensions, and it is possible to construct a building with a smooth surface;
- low consumption of adhesive;
- resistance to moisture;
- frost resistance of the material;
- combination with other building materials.
The downside is attributed small flexural strength, nonuniformity of the foam block structure, a natural shrinkage process foam concrete products and possible deviations in density. Depending on the manufacturing technology foam can give off toxic components.
Since manufacturers are now seeking to improve the quality of the material, over time there are novelties among foam concrete:
- adding crumb obtained foam polystyrene;
- if you add expanded clay granules, it turns out expanded clay lightweight concrete;
- adding chips can create arbolit;
- the use of fiberglass for additional reinforcement allows to obtain a material such as fibropenobetona;
- for insulation floor cloth apply foam concrete baby.
Note! Should not be used for the construction of the newly acquired material. Foam block is better to buy a month before the construction work. This period of time is required for drying and "maturation" of the material.
Concrete blocks or aerocrete: it is better to choose?
Foam produced from the sand-cement mixture, for which a special reagent is required. The composition is mixed and poured into molds. In production aerated It requires specially designed moisture and heat. For blowing use aluminum powder. Create an array is processed for a long time in an autoclave under high pressure. The result is a sturdy and stable material.
The basis of the material properties is heat-cellular structure. It is believed that concrete blocks densities below 750 kg / m3 can not be obtained in primitive conditions. optimal structure of the material can only be done with the new equipment, where the present high-tech process vibrovspuchivaniya. In this form the right combination of pores in the concrete. For this part of the introduced air-entraining not only the components, but also gas-forming components. vibration technology allows to achieve the same pore size. This approach reinforces the carcass strength material.
Foam concrete and aerated concrete are very similar. This lightweight materials, which differ in methods of forming air bubbles. Several different methods of installation. Concrete blocks placed on the grout, and the special aerocrete adhesive composition. But the glue required is much less than cement, and easier to work with such material. But the calculations as gazoblokov and foam blocks in 1m3 no special differences. Only if this is taken into account that gazoblok made only at the factory, and the foam block can be made at home, so the linear dimensions of the products may vary.
Unlike aerocrete foam blocks can absorb water, which affects their performance hardiness.

The choice of foam concrete blocks: the size and price
Choosing blocks, size and price per piece - are the parameters, which immediately draws attention. Such blocks may differ in their properties depending on their destination - for building walls or erecting barriers. The cost of material depends on the thermal insulating qualities and strength parameters. Most often used for the construction of buildings materials 20h30h60 sizes, price is 2700 rubles. Everything for interior partitions are suitable blocks with dimensions 10h30h60. At the same time they cost about 1,800 rubles. The amount of material measured cubes.
To calculate the cost of the material for construction work, you need to know how much 20h30h60 foam blocks located in the cube. One element includes 0,036 cubic meters. m., and in one cubic meter contained 27.8 units.
foam production technology is different. Three main ways:
- the traditional version of the finished cement added foam from a foam generator. Then the composition is mixed;
- dry mineralization technique consists of adding a foam to the dry mixture. Also, water is added. Material prepared with uninterrupted production;
- barotehnoterapii method if used, the foamable solution was mixed with water and then add the remaining components. Such a method involves the application of pressure chambers, as it requires the creation of excess pressure.
In any method of producing active material manufactured in separate units.
Air blocks: the size and price per piece
When you purchase the material is taken into account the cost of one product unit. The price is influenced foam block the size of the standard and other modifications. The cut by the elements and by drying steaming technique will be more expensive than the molded pattern. You must know that structural products will cost a bit more expensive than the insulating blocks.
The value affects not only a certain brand, but also a manufacturer. Average prices may be:
- masonry blocks - from 80 to 125 rubles;
- semiblocks - from 40 to 50 rubles;
- one cubic meter of material - from 2200 to 3600 rubles.
Approximate cost depending on the grade is represented in the table:

D800 | 3300 | 20h30h60 | 116 |
Weight 600h300h200 foam block also depends on the grade of material. For example, a product brand D600 weighs 22 kg.

How do I know how much foam block Unit
Foam concrete design different fixed price, which can vary depending on the region, delivery, purchase volume and payment terms. Thus each brand has its price, which may vary depending on the density of the material. The price may also differ substantially from region to region. The price is greatly influenced by a certain thickness of the product. To calculate the value you need to calculate the volume. Thus multiplied dimensions separate element, for example the dimensions 600 * 300 * 200. They need to multiply that in the end it turns out - 0,036 cube. After that, the cube is divided by the amount that provides a number of pieces. The unit is divided into 0,036 turns 27. If the cube cost 3,500 rubles, 3,500 divided by 27 and get 129 rubles per share.
Pre-calculate the price and size of foam blocks, you can see exactly how much material is required for the construction work. Exact calculations will allow to find a more effective solution and not spend money on unnecessary amount of output.
