Abstract:Cathodic protection is an highly reliable protection method mostly suitable for concrete structures exposed to salt-attacked conditions, such as the splash zone and above in marine environments. Nevertheless, there has been no effective method to prevent salt-induced damage for reinforced concrete structures situated in tidal zones. The applicability of cathodic protection for structures in tidal zones is evaluated both by ease of execution and protective efficiency under wave and tidal action. This paper describes the results of a study on the use of a new cathodic protection method for concrete structures located in the tidal zones. The new method was developed using anode panels together with an injection material applied to gaps between the panels and concrete surface. Using a tidal water pool, exposure tests were conducted on test specimens treated with this method. From a series of exposure tests, it is concluded that the new cathodic protection method was suitable for concrete structures in a tidal zone in marine environments.
