Encyclopedia Article. Gypsum is calcium sulfate (CaSO 4 ). Refined gypsum in the anhydrite form (no water) is percent calcium (Ca) and percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO 4 #183;2H2O) and is approximately percent Ca and percent S (plaster of paris).
When water evaporates, the minerals present in it become concentrated, and crystallize. Gypsum is formed when, due to evaporation, sulfur present in water bonds with oxygen to form a sulfate. The sulfate then combines with calcium and water to form gypsum. A Gypsum Quarry.

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, unlike cement, is a physical structure rather than a chemical structure. The needlelike gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
Gypsum nodules are probably formed by gypsum precipitation from a single point and can be polyphasic. Processes of dissolutionprecipitation affecting a gypsic parent material can also produce nodules. The constituent crystals of nodules show a variety of fabrics, but a lenticular hypidiotopic fabric is most widespread (Fig. 8).Buck and Van Hoesen (2002) describe small round aggregates

We propose that gypsum veins in Karai may have precipitated in the fractures formed due to pressure/forces generated by crystal growth. The combined results of chemical and spectral studies have shown that these techniques have significant potential to identify the pure/mineral associates/similar chemical compositions elsewhere.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4#183;2H2O. [3] It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard.

INTRODUCTION Gypsum a chemical sediment is a minor lithology distributed in the Lesser Himalaya region covering Mussoorie, SastradharaChamasari section of Dehradun (Uttarakhand). It is usually distributed as thick beds interstratified with limestones and
Jan 22, 2020#0183;#32;Gypsum is a hydrous, soft sulfate mineral, specifically a calcium sulfate dihydrate, which means it has two molecules of water in its chemical composition. This is seen in its chemical formula is CaSO 4 2H 2 0. When gypsum is heated and the water within the mineral is evaporated out, gypsum turns into a chalk or plaster, known as plaster of Paris.

#0183;#32;The major cements: composition and properties Portland cement Chemical composition. Portland cement is made up of four main compounds: tricalcium silicate (3CaO #183; SiO 2), dicalcium silicate (2CaO #183; SiO 2), tricalcium aluminate (3CaO #183; Al 2 O 3), and a tetracalcium aluminoferrite (4CaO #183; Al 2 O 3 Fe 2 O 3).In an abbreviated notation differing from the normal atomic
Drywall (also known as plasterboard, wallboard, sheet rock, gypsum board, buster board, custard board, or gypsum panel) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber (typically paper, fiberglass, or a
