Gypsum. Chemically known as "calcium sulfate dihydrate" (CaSO4ܨH2O), gypsum contains calcium, sulfur bound to oxygen, and water. The majority of gypsum produced in North America is used to manufacture gypsum board, building plasters, and cement production.
Gypsum and natural anhydrite stones are widely used in many countries of the world. These rocks can vary in terms of purity and construction and color.
Nov 20, 2009 · Gypsum vs Anhydrite Gypsum, also called hydrated calcium sulphate (CaSO4 Â· 2H2O) and anhydrite (CaSO4), also called hydrous calcium sulphate are the major minerals in the sedimentary rocks of rock gypsum and rock anhydrite respectively.1.2/5(4)

Anhydrite can be substituted for gypsum in some of its uses. Both minerals are crushed for use as a soil treatment, and in this purpose anhydrite is superior.
Gypsum (CaSO 4.2H 2O) and anhydrite (CaSO 4) are two related minerals that formed in Indiana during periodic episodes of ancient sea water evaporation in restricted basins. Large deposits of both minerals are loed in northwestern and southwester
