Abstract:
Disclosed is to 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%.
