Salts in gypsum and calcined gypsum
Journal of Applied Chemistry and Biotechnology, 1973AbstractChloride in a number of samples of gypsum and calcined gypsum has been determined by Surkevicius's method and by nephelometry. Results from the former method are confirmed. Sodium was determined by atomic absorption spectroscopy and the content found to be considerably greater than the equivalent of the chloride.

GyPSuM is a 3-D model of mantle shear wave (S) speeds, compressional wave (P) speeds, and density. The model is developed through simultaneous inversion of seismic body wave travel times (P and S) and geodynamic observations while using realistic mineral physics parameters linking wave speeds and density. Geodynamic observations include the global free

Estimation of gypsum hemihydrate content in recycled gypsums derived from gypsum boards
Journal of Material Cycles and Waste Management, 2014In order to utilize reclaimed gypsums (gypsum board waste) derived from waste plasterboards as geo-materials, thermal behaviors of the reclaimed gypsums and reagent gypsum are investigated in this paper. Furthermore, simple density measuring method of judging quality of the reclaimed gypsums is examined to determine the gypsum hemihydrate content.
