Abstract: Cathodic protection is major technique of improving the durability of the concrete structure. This article introduced the development and application of cathodic protection for reinforced concrete structures, and depicted the theory of cathodic protection. The application and research direction of impressed current protection and sacrificial anode cathodic protection were reviewed, summarizing the standard of cathodic protection and technique outline of actualizing cathodic protection.
Keywords: cathodic protection; impressed current; sacrificial anode cathodic
