Trials of intergrinding of clinker, limestone, calcined clay and gypsum have shown that the softer nature of limestone and clay and the harder nature of clinker lead to a bi-modal particle size distribution of the cement [29, 58]. While the clay and limestone particles may be ground too fine, the clinker particles remain coarse.
Gypsum cement
A group of cements that are produced from calcined Gypsum. Gypsum cement is also called gypsum concrete. In general, gypsum cements set slower and are more easily worked than Plaster of Paris. Many various formulations for gypsum cement are used. Initially, the gypsum is calcined at high temperatures to remove the bound water.
