Evaluation of the compositions and components for obtaining foam-glass ceramic materials based on aluminosilicate raw

Compositions suitable for the production of foam-teclocrystalline materials based on aluminosilicate raw materials (by the example of zeolite and diabase rocks) using a two-stage technology at temperatures not exceeding 900 ° C are considered. Criteria for evaluating the initial raw materials and compositions of glass granulate are established. It is shown that the use of aluminosilicate raw materials, when the established conditions are met, makes it possible to obtain a foam-glass-crystalline material with a density of 250 - 350 kg / m ³ and a compressive strength of up to 2 MPa.
