Popis:	Patch repair is often applied to the concrete structure deteriorated by the chloride ions. However, the macrocell corrosion may be formed, when there are a lot of chloride ions in the existing concrete. The steel corrosion in concrete progresses while depending the time. Therefore, it is effective to monitor at any time-interval. Based on the above backgrounds in this study, the analyzing method of the corrosion current is developed, to monitor the protection effect after the patch repair. The experiments are investigated in two steps. Firstly, the corrosion currents between measured from cathode to anode using the specimen with the special divided steel bar, and analyzed by this developed method, are compared. Secondly, the analyzed values and the actual corrosion or no-corrosion areas are compared. As results, 1) the analyzed values are equal to the measured values at these investigations ; 2) the analyzed corrosion area is equal to the actual corrosion area. It can be judged that quantitative monitoring method for the protect effect after the patch repair is developed.
