摘要: Electrochemical impedance spectroscopy (EIS) provides a potential approach to evaluate the overall breakage situation of self-healing microcapsules in cementitious materials. In this paper, EIS responses of cementitious mortar with insulative epoxy microparticles and conductive graphite microparticles, which was prepared for simulating the breakage situation of the microcapsules, were determined. An equivalent circuit was then proposed and the effect of breakage rate on its parameters was investigated. Moreover, the …
