What properties does aerated concrete have?
Aerated concrete is a type of cellular concrete. It consists of sand, water with gas -forming additives and Portland cement, which is a astringent.
Foam concrete is made as follows. The aluminum powder playing the role of a gas former is introduced into the mixture, which consists of binder, quartz ground and adding water. As a result of the chemical reaction between aluminum and calcium oxide hydrate, gas formation process occurs. The arising hydrogen emerges the solution. When it hardens, the porous structure is preserved. So that the material is quickly hardened and becomes quite durable, it is processed in autoclaves with warm steam at a pressure of 9 atmospheres. Air temperature in the autoclave should be 175 ° C.
Aerated concrete is used as a thermal insulation material when the enclosing structures of buildings are made.
Aerated concrete has several varieties. Each differs by the type of silica component or astringent. In gas sulcate, the lime-skipel is knitting. And the use of a gas zone of the CHP as a silicic component of ash-the appearance of a gas zone.
Aerated concrete has a number of advantages. It has good thermal insulation characteristics, very durable, environmentally friendly and has high fire resistance.
But, given the characteristics of the future building, the specialist should choose this material.
It is also important to know that the use of this material is unacceptable at the joints of heat-cold, as well as in places with high humidity. Foam concrete has a high water absorption.
If you want to build a house of aerated concrete, then you will cause damage to nature much less than during the construction of a brick or wooden building.
During the construction of any mechanism, any living area can be used just this type of concrete. In order to understand why a person comes up with new types of astringent materials, it must be remembered that every year the requirements for any design are growing, you constantly need to think about the safety of the future home and do everything possible so that the person living in it is not about anything I was worried.
