Abstract

The method is applied in particular for synthetizing hydraulic bonding agent based on natural calcium sulphate (gypsum). The calcium sulfate is heated to obtain a high proportion of anhydrite III or alpha and thermal dipping occurs. Said method consists in the following: the calcium sulfate is completely dehydrated and the matter thus dehydrated is cooled in a brutal manner. Preferably, the present invention can be used in the construction industry in order to obtain a hydraulic bonding agent that can be used as cement. 9 claims, 5 figures
