In recent years, cathodic protection has been installed to many concrete structures damaged by steel corrosion due to chloride attack. These conventional cathodic protection systems had a few defaults as mentioned bellow ; (1) It needs much man power to remove steel pieces on the concrete surface to prevent short circuit and (2) It needs skilled workers for the applications. In order to solve the problems, we developed a new anode system for cathodic protection. The anode system is installed by fixing tray-shaped anode which is composed of titanium sheet, titanium anodes and insulating frame, followed by mortar injection into the tray. The system was installed on a beam of an actual pier. As a result, it has been confirmed that the easy installation and high durability.
