The paper presents results of research of rheological properties of highly mineral-phase dispersed systems that simulate properties of soils, in a continuous shift in conjunction with the seal. It was found that the deformation of these systems is accompanied by successive stages of occurrence of discontinuities and their “healing”. Character rheological behavior and the duration of existence of discontinuities during shear deformation depend on the composition of the three-phase dispersed systems, in particular on the amount and type of additive polymer. Using tapered rheometer studies performed to determine the effect of additives polymers (epoxy resin grade ED-22 and an aqueous dispersion of polyvinyl acetate) on the structural and mechanical properties of highly disperse-phase systems containing a mineral binder (Portland M-500). The dependencies characterizing the kinetics of curing of these systems in the early stages of hardening. The effect of the addition of polymers (epoxy resin brand ED-22 and an aqueous dispersion of polyvinyl acetate) on the strength properties of the cured polymer samples of mineral compositions in compression and bending.
