On the other hand, plaster (CaSO(4)·1/2H(2)O, POP) sets quickly upon contact with water and has excellent short-term compressive strength. The aim of this study is to prepare CSC/POP composite cements and investigate the effect of POP on the compressive strength, setting time, injectability, degradation, and in vitro bioactivity of the ...
Gypsum is a soft sulfate mineral composed of calcium sulfate dehydrate, with the chemical formula CaSO4·2H2O. and as the main constituent in many forms of gypsum plaster, stucco, plaster of Paris, blackboard chalk and wallboard, gypsum board, cement factory, other chemical industries. The mineral gypsum precipitated some 100 to 200 million years ago when sea …

Here we reported a method to simultaneously control the particle size and morphology of α-CaSO 4 ·1/2H 2 O (α-HH) prepared from flue gas desulfurization gypsum by adjusting the succinic acid concentration and glycerol content under mild conditions. Succinic acid controlled the crystal morphology by adsorption onto α-HH surfaces, and glycerol controlled …

Plaster of Paris is a Calcium sulfate semi-hydrate (CaSO4, 1/2 H2O) derived from Gypsum, a calcium sulfate di-hydrate (CaSO4, 2H2O), by firing this mineral at relatively low temperature and thus reducing it to powder. CaSO4.2H2O + HEAT -----> CaSO4.1/2 H2O + 1.5 H2O. and 1/2 H2O indicates that the semi hydrate form of CaSO4
The results demonstrated that the setting time of the workable Ca (2)SiO (4)/CaSO (4).1/2H (2)O pastes was only 15 min, which was significantly reduced as compared to that of the Ca (2)SiO (4) paste (100 min), and the composite showed higher short- and long-term mechanical strength (3.25 and 37.2 MPa, respectively) than those of the Ca (2)SiO ...
The bonding nature of water in gypsum, CaSO 4 ·2H 2 O, and hemihydrate, CaSO 4 ·1/2H 2 O, was suggested by characteristic absorption bands of water and sulphate ions. The infrared spectral data indicate the presence of anion water in gypsum and hemihydrate through hydrogen bonding. Negative shifting of bending vibration of SO 4 ion and ...
