Abstract

Based on the theory of electrochemical impedance spectroscopy (EIS) and the properties of compacted cemented soils (CS) at different early curing time, an equivalent circuit model was developed to study the physical meanings of EIS parameters. EIS was also used to investigate the properties and hardened mechanisms of CS at different curing time. The relationships among the unconfined compressive strengths (UCS) of CS and EIS parameters are discussed. In addition, a useful multi-linear regression equation for UCS is proposed. The proposed model and EIS parameters help to understand the processing of cement hardened soils and the properties of CS. The study results offer more reasonable explanations for the EIS spectra.
