Abstract

This study investigated the electrical resistivity, a parameter of durability, of concrete. Electrical resistivity is the measure of the materials resistance to flow of electric current hence a high resistivity indicates a high durability of concrete. Electrical resistivity tests were conducted on Type I and Type IP concrete samples both exposed in marine environment for 30 days. Results were compared to the results of concrete samples in the submerged in NaCI solution in the laboratory. Electrical resistivities of the concrete samples were determined after curing of seven and 28 days and after exposure for 30 days. It has been found out that difference on the electrical resistivity between concrete types, curing periods and environment exposures are significant. Type IP concrete was proven to be more durable over Type I concrete in terms of electricity. Also, electrical resistivity was found out to be directly proportional to curing period. For, the comparison of electrical resistivity on different environment exposure, result was greatly affected by the non uniformity of moisture among the samples due to mishandling of samples prior to test. Moisture is a great factor in allowing flow of electricity hence it must be properly addressed in measuring the electrical resistivity of concrete.
