This study focused on developing a measurement method for electrochemical corrosion of reinforced concrete by using corrosion-monitoring sensors. Monitoring the corrosion of reinforced concrete structures is difficult, and therefore, this study is aimed to evaluate the electrochemical behavior of a Pt/Ti electrode for corrosion monitoring. Short-term laboratory experiments were performed to determine the corrosion rate of concrete mortar specimens under diverse corrosion conditions by using the corrosion-monitoring sensors quantitatively. Stable potentials were measured, and the corrosion rates were found to increase depending on the corrosiveness; moreover, the concrete resistivity decreased with the diffusion rate of chloride ions. Therefore, the corrosion-monitoring sensors accurately characterized the electrochemical corrosion behavior and reacted well with the severe corrosive environment.
