摘要： 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 Al
2 O
3 , and/or a second crystallized mineralogical phase of bicalcic alumina silicate C2AS, comprising two calcium oxides CaO for one aluminum oxide Al
2 O
3 , and one silicon dioxide SiO
2 . 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%.
