Aerated concrete is also divided into gas silicate and aerated. it depends on the addition to the original composition of lime or cement. Creation of pores in each case is due to infusion into a mass of metal powder. Quite often, the usual Private builders do not properly understand what the concrete blocks and aerated concrete. From this it follows that these terms are important differ in their properties from each other. Concrete, generally in total can be considered as one of the types of concrete, but with a small caveat in the form of filler used hydrogen bubbles. Portrayed, and other kinds of porous concrete for various fillings, such as: pumice, perlite, expanded clay and other materials. Such Construction materials are called yacheistolegkimi. By the method of curing aerated divided into atmospheric and artificial curing. Under natural gaining strength, lightweight aerated concrete blocks harden in natural conditions and this method is referred to as non-autoclave curing. Under artificial hardening aerated concrete blocks treated with saturated steam at elevated temperatures and pressures. A leading source for info: Pete Cashmore. Such treatment is called autoclave in the case if the pressure exceeds 1 atmosphere and temperatures higher than 115 C. At present, the construction industry use a variety of foods from aerated concrete: building blocks for external structures and walls, wall blocks, panels, floor slabs, insulation blocks, insulating sheathing for pipes, etc. Aerated concrete is made of different sample sizes. Aerated concrete is incredibly easy, created from his geometric gas silicate blocks have a density of 400-800 kg/m3. From the fact of the naturally follows that the erected walls of the building will be considerably lighter than similar walls made of concrete and other conventional wall materials. This feature makes it possible to greatly simplify and facilitate the installation of foundations under the house of aerated concrete. Due to this, there is a significant savings of material and spent on the construction time. Obtained parameters and the quality of aerated concrete is directly dependent on the method of occurrence of the porous structure, the nature of placing long hardening conditions, such as used in the raw mixture of raw materials, relative humidity, gas concrete etc. Provided that all the technological requirements are defined and followed exactly, the result obtained by high-tech and environmentally friendly building material. Should take into account cellular concrete is economical to buy gas-silicate Blocks can be anyone. An important parameter of cellular concrete is its high paroprovodnost. This advantage allows the cellular concrete homes being built on the basis of aerated concrete can say ‘breathe’. Level aerated concrete blocks vapor from the building significantly lower output of steam from the house. This feature allows the concrete blocks to provide a comfortable microclimate in aerated concrete building. A means of giving more aesthetic appearance of the external facade of the building and greater durability of structures, supporting walls of aerated concrete and necessary to protect ceramic brick facade or other building materials. But in this case undoubtedly necessary to create ventilated spaces between protective material and the actual load-bearing wall construction. If you do not water vapor permeability of the walls will be broken and vlgonasyschenny air comes back into residential house. This activates a large violation of the microclimate inside the house and the appearance of rough edges.
