Phase composition, microstructure and properties of aluminosilicate lightweight materials obtained by the method of burnable additives

The nature of phase formation and the properties of aluminosilicate lightweight materials created from raw materials from the Angren and Samarkand deposits of Uzbekistan are studied. The phase composition, microstructure, and physicotechnical properties of the compositions with the addition of plastic black clay and a burnable additive in the form of coke of various fractional composition were determined. It is shown that the materials of the Angrenskoye deposit are more prone to cristobalitization, which is due to the low content of alkaline oxides and a fine-grained structure. The optimum complex of properties is possessed by lightweights based on cracked clay with a burnable additive in the form of polyfraction coke. Ill. 3. Ref. 13. Tab. 2.
