Abstract : This study investigated the chloride diffusion through cement mortar and corrosion of mild steel in mortar. The chloride diffusion profile was observed in three stages: non-steady, transition, and steady states. The open-circuit potential (OCP) properties of mild steel were related to the chloride diffusion profile. The OCP value did not change considerably in the non-steady state, continuously decreased in the transition state, and stabilized in the steady-state diffusion. Corrosion measurement was terminated at a stable OCP value of -0.600 V.
