MICROMECHANICS OF THE MODIFICATION OF PHYSICOCHEMICAL AND TECHNOLOGICAL PROPERTIES OF SWELLING CLAYS

Consideration has been given to a model of formation of the microstructure of swelling clays on the basis of ideas about the action of disjoining pressure between the microparticles of clay minerals. Consideration has been given to cases of the formation of stable and unstable packings of microparticles and the transition of a structure of one type to a structure of another type. Data are presented on the use of the constructed model for control of the quality of clay raw material in construction and oil-producing industries
