The wet limestone which is a combination of calcium and water, when combined with sulfate forming calcium sulfate or gypsum is called as a chemical gypsum or synthetic gypsum.
Over 80% of the gypsum mined is used in manufactured products such as drywall. Gypsum possesses many attributes that make it an attractive construction material. Calcined gypsum can be wetted to form a paste that can be directly applied to a structure's surface or that can be molded into a desired shape; the gypsum hardens upon drying.
