Heat Treatment Process of the Flue Gas Desulphurization Gypsum and its Influence on the Properties of Cement
The Crystal Transformation of flue gas desulphurization (FGD) gypsum was analyzed by differential thermal analysis (DTA) and X-ray Diffraction (XRD). FGD gypsum was used as cement setting retarder and the influences on the properties of cement were studied by treating FGD gypsum at different heat treatment processes. The results reveal that in the case of adding the same amount, the setting time of cement shortened with the increasing of heat treatment temperature of FGD gypsum. The influence of different heat treatment processes on the strength of cements was not obvious and the strength development was good. The water consumption of normal consistency for cements changed slightly. Stability was qualified.
