In Marine environment and coastal areas, concrete structures often face chlorine salt erosion, which poses a severe challenge to the durability and mechanical properties of structural materials. Chlorine salts enter into concrete through osmosis, causing corrosion of steel bars and deterioration of concrete, resulting in a significant decline in structural bearing capacity and durability. As a new type of composite material, ECC shows great potential in strengthening and repairing RC structures due to its excellent corrosion resistance, high specific strength and good crack control effect. This paper introduces the mechanical properties and application of ECC in chlorine environment, and puts forward the optimization direction for the future application of ECC in chlorine environment.
