Abstract

Polarization Resistance (Rp) has been the electrochemical technique employed to study quantitatively the influence of Cl^- and OH^- ions on the corrosion of steel reinforcing, in a synthetic aqueous medium of similar composition to those of the concrete pore solution. Ionic strength, resistivity and their variations in function of CI^- and OH^- concentration have been chosen as more interesting solution parameters, together with intensity and potential corrosion measurements. The results showed the clear antagonistic role played by CI^- and OH^- ions on the corrosion process, which decreased as ionic strength increased.
