Abstract

This paper presents the results of an experimental investigation on the influence of curing period and chloride exposure on the electrical resistivity of Type I and Type IP cement concrete using two-electrode method utilizing a direct current source. Electrical resistivity test has been used to determine the resistance of concrete to passage of current. A high electrical resistivity indicates a fine and dense pore structure that is essential in a durable concrete. Concrete specimens having constant water to cement ratio of 0.55 were prepared using Type I and Type IP cement. Electrical resistivity test after chloride exposure showed that Type IP cement concrete performs better in resisting current than Type I for all periods. Significant increase resistivity was observed when specimens were cured from 28 days to 56 days only in Type IP specimens. The results of chloride penetration test were consistent with those of electrical resistivity test data. That is, low chloride penetration depth lead to high electrical resistivity.
