Preparation and Investigation of a Heat-Resistant Binder with a Metakaolin Additive Made of Aral Sea Raw Materials

Abstract

The purpose of the work was to obtain a heat-resistant binder with the addition of metakaolin from mineral and man-made raw materials of the Aral Sea region. The results of preparing alumina cement using kaolin, limestone, and alumina-containing waste were presented. Effective compositions of alumina cement in the kaolin-limestone-alumina-containing waste system were developed. The preparation of metakaolin with its subsequent addition during clinker grinding was investigated to improve the physicomechanical properties of a heat-resistant binder. The reliability of the results was confirmed using modern physicochemical methods.
