(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 %.
