Abstract: Despite having a number of advantages, reinforced concrete can suffer rebar corrosion
in high–chloride media, resulting in failure of reinforced concrete structures. In this research the
corrosion inhibition capability of the mixture of calcium and ammonium nitrate of steel rebar
corrosion was investigated in the simulated concrete pore solution. Cyclic polarization and
Electrochemical Impedance Spectroscopy (EIS) techniques were applied on steel concrete pore
solution containing 2 weight percent sodium chloride (NaCl). Results show that such mixtures had
higher inhibition efficiency than calcium nitrate alone. The optimum concentration of the inhibitor
mixture was determined to be 45 mgr/lit.
