Today, the main materials for constructing buildings and structures are concrete, brick, wood, and metal. Improving the performance characteristics of these materials is a priority task of modern scientific research. The paper presents the experience of modifying heavy concrete М200, М75, and М125 using polymer impregnation «Amocor». Data on the increase in the strength characteristics of the materials under study have been obtained. Tests were conducted on bending within a wide range of climatic temperatures from +20 °C to –60 °C. It was revealed that the strength of unmodified samples decreased at a test temperature of –30 °C, which is explained by the growth of internal stresses. Modification of the samples allowed for the removal of internal stresses.
