摘要：

A.C. impedance spectroscopy has been used to investigate the mechanism of hydration of portland cement paste, from 48 to 380 hours. Interpretation of a.c. measurements obtained over a wide frequency range was complimented by equivalent circuit modelling. The proposed equivalent circuit was chosen so that its RC parameters would physically represent microstructural elements of the cement paste.
