Gypsum processing and use - Humanitarian Library

2017-5-8  Gypsum is a particularly useful processed material. Its main application is as a building material, mostly produced as so-called plaster of Paris for plastering walls and making decorative features in buildings. However gypsum also has a diversity of other uses including making writing chalk, soil conditioning for agriculture, making moulds for pottery, as an additive in the manufacture of Ordinary Portland Cement (OPC), in surgical splints, in increasing the hardness of water, as an additive in certain foods such as tofu and in some types of medicines and pharmaceuticals. Its construction uses can also include external applications, such as in making walling blocks, where the climate is generally dry and not prone to the dampness that damages common types of gypsum.

Gypsum Addition - an overview ScienceDirect Topics

A larger fraction of SO 3 is added to cement in the form of calcium sulfate, either as gypsum, CaSO 4 2H 2 O, or anhydrite, CaSO 4. During cement grinding, a fraction of the gypsum may be decomposed to hemihydrate CaSO 4 ½H 2 O. The main role of calcium sulfate is to control cement setting, although strength may also be affected.
