Six cement pastes were prepared with two strength grades of cement and three water–cement ratios for electrical resistivity and compressive strength tests. The results from electrical resistivity measurement show that electrical resistivity values at 1 day and water–cement ratios follow a power function which is comparable with the relationship between compressive strength and water–cement ratio. A linear relation was established between the compressive strength at 2 days and the resistivity at 1 day, and a logarithmic relation was established between the compressive strength at 7 days or 28 days and the resistivity at 1 day. The quantitative relationships offer an alternative and non-destructive method to predict the compressive strength of pastes.
