The corrosion potential measurement and Electrochemical Impedance Spectroscopy （EIS） are explained for the observation of the corrosion of reinforced steels in concrete. In the case of environment factors in concrete, the measurements for the concentration of chloride ions and pH are applied. Besides, by using the actual concrete block, the corrosion of the steel and environmental factors are measured by these methods, and the meaning of the results are explained. Finally, the electrochemical methods are shown in the application for the actual concrete bridge.
