The cement clinker was ground together with the anhydrite in the laboratory ball mill. The cement clinker was homogenized with 15 wt% of ground limestone and different quantities of natural anhydrite (, and wt%) to give Portland limestone cement. The final sulphate contents of the cements were: wt%, wt% and wt%.
Uses of Anhydrite. Anhydrite can be substituted for gypsum in some of its uses. Both minerals are crushed for use as a soil treatment, and in this purpose anhydrite is superior. One ton of anhydrite has more calcium than one ton of gypsum because gypsum is about 21% water by weight. This yields more calcium per ton in a soil application.
Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris 2CaSO 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4). This is calcium sulfate with a ...
