Gypsum used for plaster manufacture usually contains at least 90% CaSO 4 2H 2 O, a maximum of 0.02% NaCl (salt), and approximately 2% acid insolubles. Another major use of gypsum is in the cement industry, where it is added at the rate of 2–5% to cement clinker prior to final grinding to retard the setting rate of concrete.

Gypsum is formed by the hydration of Anhydrite. The depth of hydration can range from the surface of the deposit down to three hundred metres, depending on temperature and pressure, topography and the structure of the deposit. Anhydrite is often mined in conjunction with Gypsum, but is comparatively limited in its technical applications.
