Abstract

The potentiodynamic anodic polarization was used to study the corrosion behavior of the reinforcing steel in simulated concrete pore solutions with different pH and chloride ion concentrations. The effect of chloride ions on passivity breakdown of the steel was examined by measuring the breaking potentials of reinforcing steel, and the critical chloride concentrations for depassivation were found in simulated concrete pore solutions at pH 12.50 and pH 12.00.
