Abstract
In the Philippines, studies concerning the effect of actual seawater exposure, as well as cement type and water-to-cement(w/c) ratios on the electrical resistivity of concrete structures were limited. This study aimed to investigate the effect of these parameters on concrete's resistivity. To determine the concrete electrical resistivity with different cement types and w/c ratios, DC Electrical Resistivity Test was conducted. The test used Type I and IP cement, and w/c ratios of 0.50,0.55, 0.60 and 0.65. The specimens were submerged in the coastal area of Balayan, Philippines for 60 days. To simulate this chloride exposure condition, another batch was submerged in 3% NaCI Solution located in the laboratory. The study that as the w/c ratio increases the electrical resistivity of the concrete decreases. Moreover, Type IP cement concrete had higher electrical resistivity when compared to Type I cement concrete Colorimetric testy was also conducted to check the validity of the data observed. It was then concluded that lower w/c ratio with Type IP cement yields the highest electrical resistivity of concrete.
