The efficiency of insignificant additions of clay and kaolin in relation to the production of molded and unmolded ceramic concretes, based on the use of HCBS of silica, aluminosilicate, high-alumina and corundum compositions, is shown. These additions can be made both as part of HCBS and in molding systems in the manufacture of ceramic concrete. Clay additives are especially effective in the manufacture of monolithic linings based on the Al 2 O 3 –SiO 2 –SiC–C system by vibro-pneumatic ramming. By introducing additives, it is possible to improve the rheotechnological properties of both initial HCBS of various compositions and matrix systems of ceramic concretes formed by various methods.
