Gypsum plaster – A reliable plastering alternative
Gypsum plaster is made from mineral gypsum or gypsum rock by complete or partial dehydration of water. Gypsum heated at a temperature of 150-180 degrees centigrade dehydrates and remove 2/3 rd water. The material obtained after the water dehydration is a hemihydrate (CaSO4. 1⁄2H2O) known as Gypsum Hemihydrate or Plaster of Paris.
