摘要： PROBLEM TO BE SOLVED: To semi-permanently prevent promotion of reinforcement corrosion caused by the action of microcells on defective parts of existing concrete to be repaired on its cross section, where inner reinforcement is prone to corrosion because of the shallow depth of concrete covering over the reinforcement, by using electrochemical corrosion prevention means to prevent corrosion of the reinforcement at each part to be repaired, while also facilitating the replacement and renewal of the corrosion prevention means. SOLUTION: This method for repairing concrete includes forming a space to install a corrosion preventer with a sacrificial anode in the surface part of a repair material filled part when a reinforcement-exposing recess formed by removal of concrete from a defective part of the existing concrete is filled with repair material. One end of a conductor is connected to the reinforcement exposed to the recess and the recess is filled with the repair material in such a way that the other end of the conductor is drawn out into the installation space of the corrosion preventer. The corrosion preventer is replaceably installed in the installation space.
