  • METHOD FOR MANUFACTURING A HYDRAULIC BINDER
    Publication number: 20220017414
    Abstract: 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.

  • Long-workability calcium aluminate cement with hardening promoted by a temperature increase, and related use
    Patent number: 11208353
    Abstract: Disclosed is a calcium aluminate cement, including a calcium aluminate with a first crystallised mineralogical phase of calcium dialuminate CA2 including one calcium oxide CaO for two aluminium oxides Al2O3 and/or a second crystallised mineralogical phase of dicalcium alumina silicate C2AS including two calcium oxides CaO for one aluminium oxide Al2O3 and one silicon dioxide SiO2. The mass fraction of all of the first and second mineralogical phases in the calcium aluminate is greater than or equal to 80%.
