<P>PROBLEM TO BE SOLVED: To provide a technique of an electric corrosion protection of a reinforced concrete structure configured to increase adhesion force of the thermal spraying metal adhering to the surface of the concrete structure in an anodic protection system and configured to improve the durability of the thermal spraying metal. <P>SOLUTION: A reinforcing bar 16a is embedded within a reinforced concrete structure 16. The surface 16b of the reinforced concrete structure 16 is subjected to blasting treatment. A projecting part 16c and a recessed part 16d are formed on the surface 16b of the reinforced concrete structure 16 by performing the blasting treatment. A thermal spraying metallic layer 17 is formed on the surface 16b of the reinforced concrete structure 16 subjected to the blasting treatment. The thermal spraying metallic layer 17 is composed of an alloy of aluminum (Al), zinc (Zn), indium (In). A thermal spraying metal liquid is formed by performing thermal spraying under a prescribed wind pressure (kg/cm<SP>2</SP>) in such a manner that a mean coating thickness is about 300 (μm). <P>COPYRIGHT: (C)2010,JPO&INPIT |
