The influence of impurities in FGD gypsum (> 90% CaSO 4· 2H 2 O) on the kinetics of its
transformation to α-calcium sulfate hemihydrate (α-HH, CaSO 4· 0.5 H 2 O) has been seldom …

α-Calcium sulfate hemihydrate (α-HH), a kind of advanced cementitious material, can be
prepared from calcium sulfate dihydrate (DH) in electrolyte solutions. The kinetics of the DH …

The effect of particle size on the transformation kinetics of flue gas desulfurization (FGD)
gypsum to α-calcium sulfate hemihydrate (α-HH) in calcium chloride (CaCl 2) solutions was …

Experiments and simulation results are compared in order to make precise the conditions
optimizing both the kinetics of plaster hydration and the structure of the resulting material …

To relate the dynamics of the reaction to the structure and properties of the resulting
material, we develop a three-dimensional submicrometric simulation model for plaster …

To propose a picture of plaster hydration at a submicrometric scale, we have developed a
kinetic Monte Carlo simulation model of gypsum crystal growth. Raman spectroscopy is …

Dissolution of plaster grains and precipitation of gypsum needles are described on a
mesoscopic scale in view of the optimization of reaction kinetics when gypsum needles are …

This thesis describes the investigation of the three minerals, calcium sulfate, calcium
phosphate and calcium carbonate under two bio-inspired methods, additives and …
