【 摘 要 】

AC impedance spectroscopy was used to study the setting of alkali-activated geopolymers. Results show that electrochemical theory has certain advantages in analysis of the continuous microstructural changes of geopolymers in the process of geopolymerization.Setting process of alkali-activated geopolymer was divided into several stages according to the AC impedance spectra. AC impedance spectroscopy can be used to study the effect of the modulus and amount of activator on the microstructural change.
