(57) The invention relates to a calcium aluminate cement containing a calcium aluminate with a first crystallized mineralogical phase of calcium dialuminate CA2, comprising one calcium oxide CaO for two aluminum oxides Al₂0₃, and/or a second crystallized mineralogical phase of bicalcic alumina silicate C2AS, comprising two calcium oxides CaO for one aluminum oxide Al₂0₃, and one silicon dioxide SiO₂. According to the invention, the mass fraction of said first and second mineralogical phases as a whole in said calcium aluminate is no lower than 80 %.
