Gypsum hydration: a theoretical and experimental study Calcium sulphate dihydrate (CaSO4·2H2O or gypsum) is used widely as building material because of its excellent fire resistance, aesthetics, and low price. Hemihydrate occurs in two formations of α- and β-type.

In general, the true specific gravity of semihydrated gypsum produced by dehydration under pressure is greater than that produced at normal pressure. (5) Semihydrated gypsum prepared under pressure of nitrogen in unsaturated water vapor is found to be a well developed form of α-semihydrated gypsum.

Here, we investigate the role of gypsum dehydration in the deformation of evaporitic rocks using synchrotron-based time-resolved X-ray computed microtomography (4D) imaging.

[1] We report on changes in rock permeability induced by devolatilization reactions using gypsum as a reference analog material. Cylindrical samples of natural alabaster were dehydrated in air (dry) for up to 800 h at ambient pressure and temperatures between 378 and 423 K. Subsequently, the reaction kinetics, so induced changes in porosity, and the concurrent
