Abstract

PURPOSE: To prevent the change in quality and also, to prevent the corrosion of iron reinforcing rod material, by turning the cathode current on the metallic material buried in the neighborhood of concrete structure surface at using environment of the concrete structure.
CONSTITUTION: Cathode current is turned on metallic body by using netlike metallic body which is buried in the neighborhood of concrete surface as cathode and providing with anode separating from a part or whole contrete independently for the concrete structure which is used iron structure material. For example, the iron reinforcing rod 2 is arranged in the concrete block 1 at equal spaces and the net 2 mode of soft steel, is buried near the concrete 1 face. Said body is placed in the fluid 7 and the net 2 used as the cathode, is connected with the power source 4 and then, inactive electrode made of magnetic iron oxide, is used as the anode. Elution of alkali component in the concrete is prevented by turning a current on said body and deterioration of the concrete structure is prevented by drawing near the alkaline substance in water.
