Concrete is a composite heterogeneous material. It is characterized by the presence of such structural parameters as technological cracks and residual deformations that arise during the period of obtaining the material itself during molding and subsequent hardening. In this regard, the main cause of the destruction of such materials is the irreversible growth of technological cracks to fracture or main cracks. In this regard, solving the problem of increasing the strength of concrete taking into account the adverse effects of the environment is justified and practically necessary. [1]. Dispersed reinforcement reduces the size of volumetric deformations of concrete in the initial period of hardening, and its effect is greater the higher the concentration of fiber in the cement matrix. The subject of the research is the study of the dependence of the operational properties of compositions based on inorganic binders and mineral fibers on the processes of chemical interaction in the contact zone between new formations of a hardening inorganic binder and a reinforcing component using model systems. Glass-cement compositions based on reinforcing components from glasses of different hydrolytic resistance and matrices based on inorganic binders were used as research objects.
