As a new type of cement-matrix composite material, coral aggregate concrete exhibits excellent properties, such as local material availability and enhanced efficiency, while being cost-effective. Coral aggregate concrete can be viable for construction on islands and reefs. Reinforced concrete structures generally exhibit low durability in marine environments, owing to long-term corrosion by chloride salts. Therefore, resistance to chloride ion attacks plays a significant role in improving the durability of concrete structures. As a non-destructive testing technique, resistivity is used for characterising the resistance of concrete to chloride ion penetration. In this study, the resistivity of coral aggregate concrete is measured using an improved alternating-current test method, and the improved method overcomes the limitations that is prone to polarization reaction and heating of the solution under exposure to voltage for an extended period. Porosity was used to analyze the reasons for the different resistivity values of coral concrete from micro-aspects. The resistivity model at 365 days was established considering the effects of temperature, humidity, admixture, and water-binder ratio on coral aggregate concrete. The hydration characteristics of cement and admixture were used to establish a time-varying model for predicting the resistivity of coral aggregate concrete. (C) 2020 Published by Elsevier Ltd.
