Study of the Concrete Resistance to the Action of Anti-Icing Agents

The research is aimed at studying methods for determining the strength of concrete, taking into account the effect of anti-icing agents on it. The focus of the study considered in the article is aimed at determining the patterns and mechanisms of joint work of concrete and chloride reagents that prevent the formation of ice on the body of concrete structures at the time of strength gain. In the course of the study, formulas were considered that determine the strength development of the samples under study in the context of the joint work of the above materials. Next, the coefficient of influence of anti-icing chemical additives on concrete structures was determined. The scientific novelty of the work lies in the determination of the physical and chemical mechanism that explains the causes of the destruction of concrete and its components under the influence of anti-icing reagents, as well as the identification of the main classification features of chemical de-icing agents by the nature of the aggressive effect on concrete and its components. As a result of the study, experimental studies of nine concrete samples were carried out under the influence of various conditions that affect the strength characteristics and durability of the material, and a method for calculating concrete exposed to an aggressive chloride environment was developed.
