METHOD FOR THE PRODUCTION OF HYDRAULIC BONDING AGENT BASED ON ANHYDRITE III OR ALPHA ANHYDRITE OF GYPSUM AND THE PRODUCED HYDRAULIC BONDING AGENT

摘要

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.
