This paper deals with the influence of the steel-concrete interface quality on the steel bar corrosion. Electrochemical methods including linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) were comparatively used to monitor the corrosion process of reinforcing steel in cement mortar. Experimental results show that a good quality of steel-concrete interface can significantly delay the corrosion initiation and reduces the corrosion rate. The results highlight the reasonable correlation between the impedance response and the Rp values by LPR method, but the corrosion rates obtained by EIS are lower than those results of LPR.
