By‐product gypsum from the tapioca starch process ...

By‐product gypsum derived from the tapioca starch process was calcined in the laboratory and evaluated for use in the manufacture of plaster of Paris and plaster products. The gypsum had a purity of about 98%, was fine (1 %, + 150μm) and had a low bulk density (600 kg/m 3). The laboratory calcined material had a higher than normal water requirement of 120–130 ml/100 g, and a long setting time of 65 min.

Gypsum Powder - mbpol

Gypsum powder (hydrous calcium sulfate/calcium dehydrate or CaSO4-2H2O) is a white, smooth powder that is derived from heating gypsum stone.When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate, (bassanite, often simply called "plaster") and, if heated further, to anhydrous calcium sulfate (anhydrite). Stucco is applied wet and hardens to a very dense solid.
