This investigation presents electrochemical analyses of galvanized steel reinforcements in alkaline solutions simulating a concrete-pore environment, in which a commercially available corrosion inhibitor was used. Half-cell potentials and linear polarization resistance were used to determine if the selected inhibitor decreases the corrosion activity of the galvanized coating when the galvanized rebar is in contact with high-pH solutions. Results show a remarkable decrease on passivation times between the solutions with inhibitor vs. without inhibitor.
