In this study, properties related to corrosion of embedded steel in mortar, which contains chloride around threshold chloride content for steel corrosion, were discussed. Half-cell potential, polarization resistance and polarization curve of embedded steel were measured. Half-cell potential showed a linear relationship with chloride content in mortar. Polarization resistance and grade of passivity judged by polarization curve quickly decreased at the chloride content around 0.3 - 0.4% mass percent versus unit cement mass. This indicates that the destruction of passivity film on steel surface is occurred around this chloride level, which is believed presently to be threshold chloride content for steel corrosion initiation.
