METHOD FOR STABILISING METASTABLE SOLUBLE ANHYDRITE III, METHOD FOR PRODUCING A HYDRAULIC BINDER BASED THEREON, THE OBTAINED HYDRAULIC BINDER, THE USES THEREOF AND AN INDUSTRIAL PLANT FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for stabilising a metastable soluble anhydrite III, to a method for producing a hydraulic binder based thereon, to the thus obtainable hydraulic binder, to a method for the use thereof in the cement industry and to an industrial plant for carrying out the inventive method. The method consists in stabilising a metastable soluble anhydrite III by mechanically stressing the particles thereof in such a way the crystal structure of the particles is modified and the metastable phase thereof is stabilised. Said invention makes it possible to stabilise the metastable soluble anhydrite III particles without using current steps for heating and quenching said particles.
