The paper tried to evaluate the performance of anode embedded in concrete regarding with the impressed current system. Accelerating impressed current was applied between anode and cathode within short period, in which the accumulating current density corresponded to the period of 40 years. The specimens were soaked under water because of lower concrete resistance. The instant-off potential of titan-mesh anode remained comparatively higher than that obtained based on NACE, but was within 4.0V and satisfied NSCE. Moreover, it was inclined that instant-off potential increased in the state of logarithm curve under the condition of constant applied current. After the accelerating impressed current test, it was proposed to carry out the anode polarization test so as to evaluate in detail the performance change of anode materials. And it was clearly shown that there was no degradation of adhesion between concrete and overlay after the severe accelerating test. Furthermore, the quality change of concrete surrounding anode materials was made clear by way of chemical analysis.
