THE EFFECT OF PYRO-PROCESSING PARAMETERS AND PSD ON THE REACTIVITY OF CALCIUM ALUMINATE PHASES IN CALCIUM ALUMINATE CEMENTS

摘要

Calcium Aluminate Cements (CAC), with different morphological features and Particle Size Distribution (PSD), have been analysed for their hydration characteristics by XRD, DTA / TGA and temperature rise of the neat cement paste during the hydration process. These information have been analysed vis - a - vis the setting as well as strength development characteristics of CAC. Hydration process and formation of hydrated phases, by themselves, do not explain the properties of hydrated CAC in totality.
