The water within gypsum's crystalline structure also actually helps to minimize fire damage. If a fire breaks out, heat drives the water out of the gypsum walls to cool and protect the wood or steel supporting the walls. Consequently, one of the main modern uses of gypsum is the manufacture of plasterboard (also called drywall or sheetrock ...

WHAT IS GYPSUM

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 improves soil structure by displacing sodium (and magnesium) on the surface of clay particles with calcium. Gypsum (calcium sulphate) is sparingly soluble, but the sodium (and magnesium) sulphates that form in the soil solution are very soluble. Rain (or irrigation) is required to leach these soluble salts out of the topsoil deeper

Gypsum. Gypsum is a hydrated calcium sulfate with composition CaSO 4 ·2H 2 O. It commonly occurs as a chalky powder or occasionally as small crystals. In gypsum, the structure is layered, parallel to the b direction. Tetrahedral SO 4 anions are linked by Ca cations as chains parallel to c, which form as double sheets interlayered with sheets of water molecules.

Gypsum Mineral Data

Gypsum loses mass of around 15% during calcination, i.e. if 1000 kg of gypsum plaster is calcined, approximately 850 kg plaster remains, and 150 kg of water vapor is emitted from the chimney. Gypsum found steady work in nature, becomes an unstable structure after calcination. When mixed with water again it becomes stable structure in nature.
