What is Gypsum Eurogypsum
Gypsum is composed of calcium sulphate (CaSO4) and water (H2O). Its chemical name is calcium sulphate dihydrate (CaSO4.2H2O). Gypsum can be milled mixed with water and then resume its original rock-like state. An international team of scientists has proposed a method of production of high-quality gypsum binders based on synthetic calcium sulfate dihydrate produced from industrial waste.

Gypsum The Canadian Encyclopedia
Gypsum is a mineral consisting of water-containing calcium sulphate (CaSO 4. 2 H 2 O). When calcined (roasted) at temperatures of 120-250°C, gypsum releases 75% of its water. The resulting plaster of Paris, when mixed with water, can be molded, shaped or spread, then dried or set to form hard plaster. Gypsum was used by the builders of theUncontrolled gypsum precipitation can also cause hardships during reverse osmosis processes; this issue was also addressed in the literature [9, 41, 42]. Gypsum precipitation as a side-product during the neutralization of some wastewaters was also investigated [3, 43]. From these examples, one may conclude that the precipitation The kinetics of the precipitation of gypsum, CaSO42H2O
