Abstract
Traditionally, internal and external walls of the buildings and facilities used to be built of heavy concrete and natural limestone and brick made of ceramic each type has dense structure. In Iraq it is necessary to adjust temperature during the year except for 2-3 months in residential houses and social buildings to create comfortable conditions. For a period of three months buildings must be heated and over 6 months they must be cooled. The cost of heating and cooling processes is very high. In cellular concrete technology as an adhesive used mainly cement, lime and silicon components. Now, intensive work taking place in Iraq in the restoration of buildings destroyed during the war and there are large reserves of mineral raw materials in construction places that can be recycled effectively as a result of x-ray analysis of these materials showed that their structures contain, silicon, calcium oxides and clinker materials. A sample of the materials contained separate pieces of heavy concrete as well as gravel of circular shape. These samples were collected and converted into molds within 28 h. The crusts were cut to remove the models and were then placed in pressure vessel at a temperature of a temperature of 180-200 for a period of 12 h and the pressure 10-20. Experimental studies have shown that the replacement of 30% of calc-siliceous binder with technogenic raw materials of the Republic of Iraq makes it possible to produce aerated concrete of class B1 which can used as a thermal insulation and for the installation of external walls of frame buildings.
