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. Gypsum is added to control the setting of cement. If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.
Gypsum building materials are used in all construction types (residential, non-residential, new or refurbished), ranging from complex high-tech systems to easy to install products adapted for use by the general public.
Plasterboard is used for partitions and the lining of walls, ceilings, roofs and floors. The properties of plasterboard can be modified to meet specific requirements, such as fire resistance, humidity resistance, shock resistance, etc
Plaster powder, mixed with water, manually or through the use of silo-supplied spray systems, are used to create an effective and aesthetically-pleasing lining for brick and block walls, and for ceilings. Gypsums adaptability in application lends itself to moulding and shaping. Since time immemorial, Gypsum has been used by skilled craftsmen to create decorative plaster mouldings.
Building plasterGypsum plaster is used for walls and ceilings.
Gypsum blocks are used for partitions and Gypsum tiles for ceilings.
Plaster of Paris is a white powder which hardens after coming in contact with water. The most important use of this product is in plastering in broken bone surgery. It is also used in making decorative tiles, sculpture, etc. Other uses of plaster of Paris include making slip cast refractory blows, architectural decoration for the formation of decorative friezes, cornics, columns, and other decorative features in interior finishes, making impression for dentures, inlays and for the casting of metal fillings, etc... Plaster of Paris is made from gypsum which is a non-metallic mineral. When gypsum is heated to 1210C, it loses a property of its water of crystallization and forms a quick setting cement of plaster of Paris.
As a soil additive (sometimes called land plaster) to improve the soil’s workability and receptivity to moisture, and to overcome the corrosive effect of alkalinity. Gypsum specifically benefits such crops as alfalfa, corn, cotton, wheat, and peanuts where substantial amounts of sulfate sulphur are required
As an additive in turbid water, particularly ponds, to settle dirt and clay particles without injuring aquatic life.
To create surgical and orthopedic casts
As a food additive. Gypsum (calcium sulfate) is recognized as for use as a dietary source of calcium, to condition water used in brewing beer, to control the tartness and clarity of wine, and as an ingredient in canned vegetables, flour, white bread, ice cream, blue cheese, and other foods
As a color additive for drugs and cosmetics
A primary ingredient in toothpaste
