What is Impedance Spectroscopy in Cement Hydration about?

This document discusses impedance spectroscopy techniques for studying the evolving microstructure of cement-based materials during hydration. It proposes that the high relative dielectric constants observed after initial set are due to dielectric amplification related to the distribution of pore sizes and thickness of hydration product layers separating pores. Conductivity is related to porosity fraction, pore solution conductivity, and pore interconnectivity. Composite mixing laws and pixel-based digital
