PHASE COMPOSITION, MICROSTRUCTURE, AND PROPERTIES OF ALUMINOSILICATE LIGHT-WEIGHT MATERIALS OBTAINED BY THE METHOD OF BURNING ADDITIVES

摘要

We study the character of phase formation and the properties of aluminosilicate lightweight materials produced from the raw materials of the Angren and Samarkand deposits in Uzbekistan. We determine the phase composition, microstructure, physical, and technical properties of compositions with admixtures of plastic black clay and burning additives in the form of coke of various fractional compositions. It is shown that the materials from the Angren deposit are more susceptible to cristobalitization, which is explained by the lower content of oxides of alkali metals and their fine-grained structure. The optimal complex of properties is exhibited by the lightweight materials based on kaolin clay with burning additives in the form of polyfractional coke.
