PROBLEM TO BE SOLVED: To provide a repair method for a concrete structure, wherein the repair of the cracked concrete structure and the management of the repair can be easily and surely performed. SOLUTION: In this repair method, the concrete structure 1 is repaired in the following processes: a holder 12 for holding an electrolytic solution 11 is arranged on a surface 1a of the concrete structure 1; an electrode 13, which is installed in the holder 12, is set to be an anode; a reinforcing bar 2 inside the concrete structure 1 is set to be a cathode; and an electric current is applied between the anode and the cathode. A pH of the electrolytic solution 11 is measured, and the application of the electric current is finished when the pH reaches a prescribed value or below. Preferably, the prescribed pH is set in a range of 5.5-6.5. COPYRIGHT: (C)2004,JPO&NCIPI
