Abstract: 
The process of curing has remarkable influence on the surface performance of concrete. By embedding electrodes at different depths from the surface of concrete, and testing the resistivity of concrete in different curing process in immersion state under water, the resistivity changes were analyzed and discussed. It is shown that there is significant relationship between curing process and the resistivity changes of surface concrete along with ages. Also, there is remarkable correlation between curing process and the resistivity changes of surface concrete in immersion state under water, especially, high w/c ratio concrete. It is considered that the curing process can be real-time monitored by comparing both the changing rate of concrete surface resistivity at stand curing condition and the concrete surface resistivity at the practical application, as well as evaluating the concrete curing efficiency.
