Technical Information Product and Systems Technology

With gypsum, combined water is driven off in calcination to yield stucco (CaSO 4 • 1/2H 2O) or dead-burned gypsum (CaSO 4). In limestone calcination, carbon dioxide is lost to form quicklime (CaO) or dolomitic quicklime (CaO • MgO). Calcined Gypsum Partially or fully dehydrated gypsum used as a cementitious base for gypsum plaster.

A Study of Calcination of Gypsum Wallboard | The NAFI Blog

Nov 29, 2016 · The prevalence of gypsum wallboard in fire scenes makes it a potentially valuable source of information to fire investigators when assessing a fire scene. The exposure of gypsum wallboard to heat from a fire can result in calcination, which in turn can theoretically be correlated to the total heat exposure to that area.
