The influence of carbonate additives on the formation of the structure of cement stone

Abstract

Concrete and reinforced concrete hydraulic structures located in marine areas and transport structures where road salt is regularly used are exposed to chlorides. As is known, chlorides are hazardous substances for concrete structures, as they accelerate the corrosion processes of steel reinforcement. Penetration of chlorides into concrete leads to a series of chemical reactions that cause corrosion of reinforcement and, ultimately, destruction of concrete. Understanding the mechanisms of chloride penetration into concrete, the mechanisms of chloride corrosion and the development of appropriate protection strategies are key tasks in the context of durability and operational safety of the mentioned structures.
