&nbsp;&nbsp;In order to study for corrosion behavior of reinforcing steel with oxidation layer, the characteristics of corrosion behavior were measured by polarization resistance method and cyclic potentiodynamic method.<BR>&nbsp;&nbsp;Experiments were done with various NaCl concentrations and with immersion time in simulated concrete pore solution(SPS).<BR>&nbsp;&nbsp;Rebars were coated by epoxy except corrosion area and except connecting area with potentiometer.<BR>&nbsp;&nbsp;The corrosion potential of rebar with oxidation layer was higher than that without oxidation layer and it also showed two anodic-nose.<BR>&nbsp;&nbsp;By the result of potentiodynamic method, the potential curve shifted to low potential region with time and anodic-nose was appeared with 3% NaCl solution after 15 days.<BR>&nbsp;&nbsp;By the result of cyclic Potentiodynamic method, the types of corrosion were different according to concentrations.
