Based on the current status of chloride ion erosion in coastal areas of China, this paper points out the necessity and significance of the current research on the corrosion of reinforced concrete structures under chloride ion environment. In the coastal environment, reinforced concrete structures are in use. The durability problems caused by the erosion of chloride ions and the research and development of related disciplines at home and abroad have been reviewed. Based on the actual conditions, based on the electrochemical theory, the basic corrosion mechanism and corrosion of reinforced concrete structures under chloride ion environment have been studied. process. Finally, based on the results obtained, the corrosion mechanism of chloride ions, the brief description of the diffusion of chloride ions in structural concrete, and other issues were studied, and some protections and countermeasures against atmospheric ion corrosion were proposed.
