USE OF CLAY MATERIALS IN THE CONSTRUCTION OF PROTECTIVE BARRIERS AT RADIATION HAZARDOUS FACILITIES

The article discusses the types of mineral raw materials that can be used to manufacture clay barrier materials. The paper evaluates the characteristics of materials governing the performance of clay barriers: grain size, mineral and chemical composition, physical, mechanical (in dry state) and colloidal properties, stability in the environment. It considers the methods used to identify these characteristics and provides relevant examples. 

Keywords: bentonite, kaolin, barrier mixture, bulk density, moisture content, colloidality, moisture capacity, fluidity, deformation, internal friction, residual adhesion, specific surface area, clay colloids, physicochemical stability, climatic effect, radioactive waste.
