<P>PROBLEM TO BE SOLVED: To provide an anticorrosive construction method of a reinforcing bar inside salt-damaged reinforced concrete the resistance of which to salt damage is improved by imparting an excellent anticorrosive effect to a reinforced concrete structure and suppressing the corrosion of the reinforcing bar inside the reinforced concrete. <P>SOLUTION: The anticorrosive construction method of the reinforcing bar inside the salt-damaged reinforced concrete comprises the steps of: covering the surface of the reinforced concrete with a cross section repairing material having the electric resistivity of 0.1-10 times that of the concrete in the reinforced concrete structure; installing a sacrificial anode material inside the cross section repairing material; additionally arranging a porous material, which contains an electrolyte solution having the pH enough to avoid formation of passivity of the sacrificial anode material, around the sacrificial anode material; and electrically connecting the sacrificial anode material to the reinforcing bar inside the reinforced concrete, and further comprises a step of applying an organic-inorganic combined coating film curing agent to the surface of the cross section repairing material-covered reinforced concrete. <P>COPYRIGHT: (C)2011,JPO&INPIT |
