The calcination process between well-proportioned argillaceous and calcareous substances leads to the production of clinker. Portland cement is obtained when the produced clinker is mixed together with a predefined ratio of gypsum and milled together in a ball mill. The chemical composition of Portland cement involves both major and minor oxides .

Slabs of PM were ground in a ball mill to a powder with a grain size of between 600–1700 μm. The results of the treated materials with the particles were evaluated by dissolution experiments in which the rates of dissolution of the specimens were measured in undersaturated solutions of calcium carbonate (pH 6.50, 25.0 °C).
The present work investigated the differences in the composition and internal microstructure of four types gypsum rock—fiber gypsum, transparent …
Gypsum. Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and ...
Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
