| Research Abstract |
A galvanic anode system is one of the ways of cathodic protection used to protect metal from corrosion using galvanic or sacrificial anodes. However, it is so difficult to control the corrosion reaction of sacrificial anode metal in the system that only seldom attempt has been tried for actual concrete structures. In order to apply this system more effectively in the fields of maintenance of concrete structures, electrochemical properties of sacrificial anode metals in several environments must be considered in detail. In this study, considering the system as a new coating system with a function of Cathodic protection, the influence of anode types, environmental conditions and deterioration levels of the concrete structure upon the effect of the system were clarified by experimental examinations.
