Properties of aerated concrete

Aerated concrete blocks are a variety of cellular concrete, produced by switching the dough by knitting gases. They are released with a chemical reaction in which the gas former is involved – the powder of aluminum.

Aerated concrete is often confused with foam concrete and gas-slander (TheDifferencechem -otlichaetsya-Gazobeton-Gazosilikata), but they, of course, have their differences. Blocks made of aerated concrete are good: the standard unit has a size of 300x250x600, and easily replace 22 bricks. The advantages immediately need to supplement the faster construction of the walls of the house – with the brick, it will still take a noticeable more time to build the wall of the same size. Moreover, 22 bricks weigh not 30 kg at all, but 100, as a result – the foundation under aerated concrete requires less powerful than under a brick house.

The labor intensity of work with aerated concrete walls will also be lower.

The main properties of aerated concrete

Thermal conductivity due to the porous structure is high. The heat -insulating effect is helped by the air located inside the blocks. In a house with aerated concrete walls, the cost of heating will be reduced by 30%;

The property of heat accumulation – the structure is arranged in such a way that it is capable of accumulating heat from the sun, as well as from home heating. As a result, in winter you can save fuel, and in the summer a pleasant coolness will come from the walls;

Sound insulation: when compared with brick masonry, then the soundproofing properties of blocks are better than brick by 10 times;

High fire safety: aerated concrete is non-combustible and is able to withstand the direct effect of fire for five to seven hours, it is also able to protect the metal structures from combustion;

Frost resistance: the pores of aerated concrete are able to displace moisture and ice from their base, without destroying the material;

High environmental friendliness of aerated concrete: it is produced from mineral materials, its composition lime, sand, cement and aluminum powder. It is noteworthy that aerated concrete from building materials takes second place in environmental friendliness after a tree;

economical consumption of material, as well as high speed of wall construction.

Masonry of a gas concrete partition at prices is beneficial, and also has a large number of positive properties, which makes the use of aerated concrete in construction with a very frequent event.
