PROCEDE DE FABRICATION D'UN LIANT HYDRAULIQUE
Disclosed is a method for manufacturing a hydraulic binder including a calcium aluminate, which involves: a) providing a composition including a lime C source compound and an alumina source compound, the composition including at most 95% lime C and alumina, and at least 23% alumina, by weight relative to the total weight of dry matter of the composition; b) placing the composition provided in step a) in a moisture-saturated environment, at a hydration temperature of between 40° C. and 150° C., so as to precipitate hydrated phases containing at least one aluminium oxide combined with a calcium oxide and with water; and c) subjecting the precipitates obtained in step b) to a baking temperature of between 200° C. and 1300° C., for at least 15 minutes.
