In this paper, electrochemical impedance spectroscopy (EIS) was adopted as a nondestructive testing method for measuring the electrical resistance and evaluating the development of compressive strength of cementitious materials.The impedance spectroscopy parameters make it possible to analyze the evolution of the microstructure and the formation of hydration products.At the same time, results of the compressive strength were obtained to evaluate the applicability and the reliability of the EIS model.Based on the microstructure analysis, correlation between electrical resistivity and compressive strength has been established, a linear relationship can be obtained as Y=a X+b.It can be concluded that the electrical resistivity curves dynamically reflect the internal microstructure formation and strength development in cementitious materials and it is possible to predict compressive strength quantitatively.
