Aerated concrete? Reviews positive!

Aerated concrete blocks are becoming increasingly common in the construction of private houses and cottages. But why aerated concrete? The opinions of specialists testify to the multitude of advantages that this material possesses in comparison with other wall materials :

• Aerated concrete allows you to build economical single-seamed walls quickly and without the use of heavy equipment , which meet the general requirements for heat insulation in Europe.
• Aerated concrete, for the production of which only concrete, aluminum powder, quicklime, water and sand are used, is an environmentally friendly material. Aerated concrete blocks, reviews of specialists from Rospotrebnadzor confirm this, does not emit any harmful substances into the atmosphere. Living in rooms with gas-silicate walls does not harm health.
• The walls of this material serve for a very long time, are not afraid of fire, have excellent load-bearing capacity and vapor permeability.

Let's try to compare aerated concrete with other materials for the erection of walls.

What is more preferable: foam concrete or aerated concrete blocks? The characteristics of the materials indicate that the foam concrete in its pure form can not be used for the construction of load-bearing walls, and aerated concrete blocks can be used. They are characterized not only by high bearing qualities, but also by low thermal conductivity, by an exact geometric shape. It is the exact shape that allows you to carefully adjust all the blocks, providing an accurate single-seam masonry. Foam concrete eventually settles down, and aerated concrete (reviews about it are unanimous) shrinkage practically has no. The blocks of aerated concrete are perfectly processed: they can be cut, sawed, in them it is possible to hammer nails. Foam concrete crumbles and does not hold any fasteners in itself. The chemical composition of air in the room, for the construction of which aerated concrete is used (Rospotrebnadzor's reviews confirm this information) is similar to air in premises built of wood.

Why more and more consumers choose not brick, but aerated concrete? Comments from potential housing builders give the answer to this question:

• Aerated concrete costs less;
• It is lighter than bricks and does not require the installation of heavy equipment;
• Blocks of aerated concrete are larger than bricks, so construction is faster;
• In a house made of aerated concrete, a heavy foundation is not needed.

The conclusion is simple and clear: expensive brick is not as popular today as aerated concrete. Comments from consumers of building materials - a clear proof of that.

If we compare aerated concrete with the recently popular and inexpensive polystyrene concrete, the advantages of the former will also be obvious. Expanded polystyrene concrete is harmful to health. It does not possess such a high vapor permeability as is characteristic of aerated concrete. Therefore, in premises of PPSB there is always increased humidity, condensate is collected. He is unstable to fire, the walls of it are fire dangerous. When burning, polystyrene concrete separates corrosive and very toxic substances, and aerated concrete does not burn at all.

It is interesting that aerocrete for a variety of technical and chemical characteristics is superior even to wood. The tree is susceptible to shrinkage and cracking. The house, built by their tree, should be "defended" for at least six months, which significantly lengthens the construction period. It quickly ignites, and, impregnated with special anti-inflammable compounds, releases harmful substances. The tree is exposed to biological pests, therefore it needs constant processing with varnishes, septic tanks, mastics. On the ecology of housing in this case it does not go. Untreated wood is very short-lived. All these defects are absent in aerated concrete.

Aerated concrete blocks help to build high-quality housing quickly, cheaply, for a long time.
