Abstract (en)
[origin: WO2020089564A1] The invention concerns a method for manufacturing a hydraulic binder comprising a calcium aluminate, which involves: a) providing a composition comprising a lime C source compound and an alumina source compound, the composition comprising 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; c) subjecting the precipitates obtained in step b) to a baking temperature of between 200°C and 1300°C, for at least 15 minutes.
