Ceramic Bricks of Semi-Dry Pressing with the Use of Fusible Loams and Non-Traditional Mineral Raw Materials

Abstract

The possibility of using aluminosilicate raw materials and ash and slag waste of thermal power plants in the production of ceramic bricks is considered. The physicochemical processes taking place in the preparation of ceramic materials based on ash and slag waste are studied. In order to accelerate the process of sintering a ceramic material, the possibility of using an additive of sodium silicate lump was investigated. Its influence on the technological properties of ceramics of rational composition was studied and the expediency of introducing this additive into the mixture in the amount of 10% was established. The dependences of fire shrinkage on the amount of ash and slag waste at a firing temperature of 1050 ° C are determined.
