KGS--Gypsum in Kansas--Uses and Summary
Feb 20, 2018Uses and Manufacture of Gypsum. Although considerable gypsum is used in the raw state, most gypsum is calcined before it is used. Calcining consists of heating the mineral to remove the chemically combined water that it contains. This process and its chemical reactions have been described briefly in this report.

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.

Gypsum Wallboard Chemical Additives
Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needle-like gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
