This paper focusses on the influence of cement type (Ordinary Portland Cement, OPC; and Fly ash based Portland Pozzolana Cement, PPC), polycarboxylic ether (PCE) superplasticizer and calcium nitrite inhibitor (CNI) on the corrosion resistance of cracked reinforced concrete in chloride-rich environments. U-shaped specimen reinforced with 12 mm diameter bar was used for initiating flexural cracks of required width. Accelerated impressed current test results show that the weight loss of rebar for concrete with PPC is found to be significantly lower and the weight loss of rebar for concrete with CNI is significantly higher, when compared to that of the weight loss of rebar for concrete with OPC alone. The results show that the relative service life of PPC based concrete is found to be at least twice that of corresponding OPC based concretes.
