Study of Structural-Sorption Properties of Materials Made on the Basis of Clay-Ultradispers Additional Mixture

Abstract

The article is devoted to the research of structural and sorption properties of the material obtained on the basis of a mixture of clay and ultradispersed additives. For this purpose, one of the most common methods of regulating hydrophilicity was considered to be the use of surface-active additives. To determine the sorption capacity of the ceramic mass, both hydraulic clays, which are widely used in the building ceramics industry, and bentonite clays with high sorption capacity were used. According to the experiments, the use of surface-active additives led to an increase in the adsorption of water by the ceramic mass. The influence of increased water adsorption on the properties of the ceramic material was determined experimentally. Since the properties of ceramic materials, such as absorption and density, reflect their structure, the effect of surface-active additives on these properties was studied, and it was determined that the density of the ceramic material increased significantly. Surface-active additives increase the plasticity of the ceramic mass and, consequently, improve the structural and technical properties of the material.
