Gypsum. Source: PCA, 2003. Grinding. Clinker is ground with gypsum (calcium sulfate) to produce portland cement; Fine grinding is necessary for high early strength. 85-95% -325 mesh (45 microns); ~ 7 trillion particles per pound. Gypsum absorbs water and prevents setting of C3A during shipment. Source: van Oss and.
Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO4.H2O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO4). This is calcium sulfate with a trace of bound.
