Different researchers make different conclusions on the reinforcement corrosion parameters after electrochemical repair. In order to give a reasonable explanation of the phenomenon, anodic polarization curve (APC) is employed to study the effects of electrochemical repair methods on polarization parameters of reinforced in simulated pore solution. The results show that the effects of different treatment duration and current density on the anodic polarization current and potential of the reinforced after various treatments. After the treatment, the anodic polarization current and reinforcement potential change a lot: the greater the power, the more the increase of anodic polarization current, the more the reduction of reinforcement potential. Over time, this change gradually weakens until smooth, which is a depolarization process, and usually takes 42 days. After depolarization, the polarization current of the reinforced is still relatively large compared with that before the treatment, usually 2~5 times, that shows the treatment can increase the polarization area of the reinforced, also 2~5 times; however, reinforcement potential changes little. By analysis of surface morphology of the reinforced, it is found that the surface of the reinforced becomes rougher after treatment, surface area increasing will make the polarization area increase, which is a reasonable interpretation of polarization current increasing after treatment.
