Abstract
The pitting corrosion current of reinforcing steel is measured under natural corrosion conditions in Ca(OH)2 solutions in presence of Cl− as aggressive ions and CrO42-,HPO42-,NO2-,WO42-andMoO42- as inhibiting anions. The corrosion current starts to flow after an induction period which depends on solution composition (concentration, pH and presence or absence of the aggressive and the inhibiting anions). The limiting corrosion currents increase with increasing the Cl− ion concentration and decrease with increasing the pH and inhibiting ions concentration. The inhibition efficiency of the studied inhibiting ions increases in the following order: CrO42-
