Production of foam concrete products and monolithic concreting from them requires foaming agents that have the properties of the obtained foam with a sufficient value of its criteria (multiplicity of foaming, stability of foam for a certain period of time); its compatibility with Portland cement and its hydration products; with hydrated lime, etc. Insufficient properties of the foam can be compensated by the introduction of corrective and stabilizing additives.
One of the leaders of wall materials in the modern market, which combines high constructional and thermal insulation properties, is cellular concrete, in particular non-autoclave hardening. Improving efficiency of cellular concrete as a heat insulating material is, above all, in the maximum possible decrease in average density, while providing a certain level of physical and mechanical indicators necessary for the manufacture of products in the form of slabs.
One of the priorities of modern construction industry is to increase the heat-shielding properties enclosing structures and reduce construction costs. Solving these problems is possible through the use in the manufacture of insulating exterior walling and structuralinsulating non-autoclaved aerated concrete from technogenic waste, especially fly ahes and slag thermal power plants.
