The review of early hydration of cement-based materials by electrical methods

This paper reviews the evaluation of hydration of cement-based materials by means of electrical methods from the view point of direct and alternative current methods. The merits, demerits and application scenarios of electrical methods for hydration characterization are described. Influencing factors (pore solution conductivity, porosity, pore size distribution and pore connectivity) of electrical methods are briefly commented. Besides, the predictions of setting time and shrinkage, and the determination of hydration stages by electrical methods are presented. The combinations of some mainstream computer simulations and electrical methods are reviewed.
