Abstract

The most recent use of impedance spectroscopy for studying the evolving microstructure of cement-based materials during hydration is demonstrated. Features of the spectra are discussed and related to components of the microstructure with the help of pixel-based computer modeling techniques. It is proposed that the enormously high relative dielectric constants observed just after set are the result of dielectric amplification and are related to the distribution of pore sizes and the thickness of product related to the volume fraction of porosity. Procedures for predicting the conductivity of the pore solution and for subtracting out electrode lead effects at high frequency are discussed.
