It was investigated that the impregnation of concrete with polymer compositions is determined by viscosity, adhesive strength, polymerization speed of the monomer, distribution of pores in the volume of concrete, and penetrating ability of composition components. The peculiarities of the porous structure of concrete reinforced with a polymer composition and the depth of penetration of the polymer were studied using electron microscopy. A change in the strength and deformability characteristics of concrete was determined. As a result, the compressive strength of concrete increased by 9 ... 20%, the initial modulus of elasticity increased by 27 ... 37%, the relative deformations decreased by 10 ... 25%, and the tensile strength of concrete increased by 30%. © 2024 The Authors.
