Gypsum is a soft sulfate mineral composed of calcium sulfate dehydrate, with the chemical formula CaSO. 4· 2H2O Gypsum is widely used in construction because of its ability to hold nails, screws and other small parts. Some gypsum products are used to make drywall, plaster foundation and facing materials, concrete and stucco.
Product Description:
Gypsum is Calcium Sulphate Dihydrate (CaSO4.2H2O) deposited in sedimentary layers on the seabed. Under high pressure and temperature, Gypsum turns into Anhydrite (CaSO4). Gypsum / Anhydrite are produced from open-cast mines or underground mines. Gypsum is normally only screened to remove â??finesâ?? (mainly mudstones), then crushed and finely ground for various applications. Gypsum is an indispensable component of Ordinary Portland Cement as it has a great influence on water consumption of standard consistency and strength simultaneously. During the cement manufacturing process, 4%-6% of Gypsum (by weight) in crushed form is introduced during the final grinding process upon cooling of clinker. It plays an important role in controlling the rate of hardening or setting of cement. If not added, the cement will set immediately after mixing of water leaving no time for concrete placing. Over 60% of Gypsum produced across the world is used in cement manufacturing. Other applications include the production of plaster, plasterboards, Gypsum fiberboard, and Gypsum blocks. It can also be used as a soil conditioner and has various other specialized applications. An important property of Gypsum is that it is naturally fire-resistant.

Applications:
Finishes applied to plasterboard surfaces can have a significant effect on the perceived quality of the installation, particularly where critical lighting conditions exist.
Textured or heavy patterned finishes tend to hide imperfections
Matt finishes minimize imperfection visibility
Semi-gloss and gloss finishes highlight imperfections
Light colours are less likely to show imperfections and impact damage
