Dielectric properties of fly ash geopolymers with two types of potassium activators
The interest for geopolymer materials for cement and binder applications has increased in recent years due to their compliance with green chemistry and low cost. In this study, we show the dynamics of water in fly ash-based geopolymers using low-temperature broadband dielectric impedance spectroscopy (BDS). Confined water has a major influence on properties such as durability and performance because it affects the porosity and pore size distribution. Hence, the dielectric measurements allow probing of the porous structure of the geopolymers.
