Reinforced concrete structure system can be used under a wide range of environmental influences and also brings significant durability problems in terms of concrete and reinforcement [1]. Corrosion is inevitable in steel construction structures. However, its effects and results can be minimized by providing effective protection [2]. In the study, the corrosion behavior of mild reinforced concrete steel in solution prepared by adding NaCl at %0.06, %0.09, %0.12 and %0.15 concentrations in concrete pore water, respectively. Electrochemical measurements were made using 3 electrode method. With these measurements, the open circuit potentials of the mild reinforced concrete steel, Nyquist curves and Tafel curves were investigated and the results were compared proportionally. When the effects of %0.06, %0.09, %0.12 and %0.15 NaCl on the mild reinforced concrete steel were investigated by electrochemical methods, respectively, added to the concrete pore water at different concentrations. It was observed that as the amount of NaCl in the concrete pore water increased, the corrosion current density increased in reinforced concrete steel.
