Abstract

This study investigates the effect of volcanic pumice, Type I and Type IP cement and varying curing period on the corrosion resistance of a cement concrete. Impressed voltage test was carried on cement concretes having a 0.50 water to binder ratio to determine their corrosion current curve, time to initiate crack and highest value of current acquired within testing duration. For a constant curing period, analysis shows that volcanic pumice improves resistance to corrosion of both Type I and Type IP concrete. Also, Type IP yields lower corrosion curve than Type I on normal and volcanic pumice concrete specimen. Thus, volcanic pumice and Type IP is effective in increasing resistivity to corrosion of cement concrete. Furthermore, analysis on volcanic pumice concrete indicates that the effect of increasing curing duration raises resistivity against corrosion though minimal. The study also suggest that Type IP volcanic pumice curd on 56 days is most resistive to corrosion considering it yields the lowest maximum current value acquired.
