Drywall is composed of gypsum plaster pressed between a paper lining. The key material is gypsum (calcium sulfate), which is available in different hydration levels, and in anhydrous form. Natural gypsum stone is calcium sulfate-dihydrate (CaSO4*2H2O). The anhydrous calcium sulfate can be found in nature as anhydrite (CaSO4).
Gypsum board manufacturers are increasingly relying on "synthetic" gypsum as an effective alternative to natural gypsum. It is estimated that roughly 45% of the gypsum used by U.S. manufacturers in 2010 was of the synthetic variety. Synthetic gypsum and natural gypsum have similar general chemical compositions (CaSO 4 ·2H 2 0). The vast ...
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.
Mar 14, 2012· By any name--drywall, wallboard, or plasterboard--gypsum products may not be as innocent as we once thought. Drywall, which makes up 15% of demolition and construction waste, leaches toxins and releases hydrogen sulfide gas in landfills.

The Role of Gypsum as a Soil Amendment—Gypsum is hydrated calcium sulfate (CaSO4 • 2H2O), and is often marketed as a soil "conditioner" for improving soil "tilth." Compared to most other calcium-rich soil amendments, such as limestone, gypsum is relatively soluble in water, dissolving up to 2 g per liter. The solubility of gypsum, when either incorporated or surface applied ...

Gypsum is calcium sulfate (CaSO4). Refined gypsum in the anhydrite form (no water) is 29.4 percent calcium (Ca) and 23.5 percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO4·2H2O) and is approximately 23.3 percent Ca and 18.5 percent S (plaster of paris). Gypsum fertilizer usually has other impurities so grades are approximately 22 percent Ca and 17 ...
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
Gypsum boards or plasterboards are typical materials used to build light walls. The production process is based on gypsum hydration technology. At the very beginning of the process dehydrated calcium sulfate (gypsum) is converted into CaSO 4 ·0.5H 2 O by heating. Once dehydrated, gypsum is mixed with water, starch, a ing agent, and other additives.
