Electrochemical properties of embedded steel bars in the various materials were evaluated in view of the chloride attack. The measured items were (1) anodic polarization curve, (2) polarization resistance, (3) resistance of material, and, (4) potential. Also, the meanings of the measured values were investigated. The conclusions were as follows ; (1) Using resin as coating materials for concrete as well as for steel bars, electrochemical properties of the embedded steel bars were improved. The properties, however, were getting worse gradually. (2) Concrete mixed with blast furnace slag cement showed excellent properties among the concrete used. (3) There were many difficulties in evaluating the measured values, especially the potentials.
