摘要：

The hydration kinetics of pure synthetic orthorhombic anhydrite, obtained by calcination of synthetic Merck Gypsum, depends on the temperature of preparation, on the mechanical activation by grinding and of the nature of foreign cations in solution, used as chemical activators. Concerning this last factor, it is shown that the higher the 'z/r' parameter, characterizing the foreign cation (z the charge and r the ionic radius), the higher the reactivity of the solid.
