Raw Gypsum is chemically known as Calcium dihydrate (Ca[SO4].2H2O) or Dihydrate Gypsum, and commercially, it is known as Plaster. It consists of white, colorless, or transparent crystals readily used in wide applications industrially and commercially.
gypsum products gain momentum during the last decades. Though gypsum has proved to be the best and cost effective construction material due to its excellent physical property, it has a number of limitations such as high permeable to water, porous nature, low compressive strength, low flexural and tensile strength.
Major raw material of gypsum is natural dihydrate gypsum (CaSO 4 · 2H 2 O) and natural anhydrite (CaSO 4) (also named hard gypsum). Both are named as raw gypsum. Common building gypsum is hemi-hydrate (CaSO 4 · 1 2 H 2 O), decomposed from dihydrate and anhydrite when heated to 1500-1700 ºC. So it is also called plaster of Paris or hemi ...
