Modification of argillous raw materials by additives comprising carbonates

Abstract

In order to improve technological and drying properties of argillaceous raw materials and to produce face brick of light color shades from low-melt and red-burning clay, a modification of carbonate-containing additive, in a form of oil-slime utilization product, was carried out. An influence of a concentration of an additive on structure and properties of a modified mixture is discussed. Structure of ceramics and chemical composition of minerals formed during burning is studied, their influence and an influence of organic component of the additive on a change of color and properties of ceramic brick, manufactured by means of plastic molding method, are identified.
