Description
Summary:Electrical property measurements have widely been used to study the early hydration of the Portland cement and in the study of admixtures on hydration. In this wor, the electrical response of chemically and thermally activated fly-ash is presented to highlight how this testing methodology could be extended to study phase transition (i.e., liquid to solid) and reaction kinetics of this group of materials from initial gauging through setting and hardening and as a technique in the assessment of a particular activator or combination of activators.
