The hydration process of concrete has been studied using a non-contact electrical resistivity measurement. Cement hydration stages have been classified and the hydration mechanism has been interpreted based on the analysis of resistivity development curve and the investigations of microstructure. The proposed concrete conduction model shows that the degree of hydration dominates concrete resistivity. It also proposes some practical applications of the resistivity measurement in the activity evaluation of mineral admixtures, the selection of a superplasticizer and the determination of concrete ...
