摘要：
Coal flotation wastes from of OOO MMK-UGOL' were studied using a semiquantitative method; air and fire shrinkage, sintering, refractoriness, and tensile strength were determined. It has been proposed to use the wastes in an amount of 10-30% as an inert and combustible additive to clay mixtures for ceramic brick production by a semidry method in order to produce bricks of M100, M75, and M50 grades. The addition of wastes increased the porosity of finished products, improved their heat-insulating properties, and decreased shrinkage.
