In this study, electrochemical characteristics regarding to corrosion of embedded steel in mortar are experimentally evaluated. The corrosion behavior of steel bar was evaluated through electrochemical techniques, half-cell potential, corrosion current density, and anodic polarization curve. Also, the extent of corroded area of steel bars was measured. Major test variables are chloride content in mortar and water-to-cement ratio of mortar. Chloride content was set either by ％-cement mass or total weight of mortar. The result showed that chloride contaminated mortar expressed in total weight of mortar were more readable to evaluate corrosion of steel bar by using electrochemical techniques. In addition, water-to-cement ratio affects electrochemical behavior and corroded area.
