Long-workability calcium aluminate cement with hardening promoted by a temperature increase, and related use

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 Al2O3, and/or a second crystallized mineralogical phase of bicalcic alumina silicate C2AS, comprising two calcium oxides CaO for one aluminum oxide Al2O3, 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%. 本发明涉及种包含铝酸钙的铝酸钙水泥，该铝酸钙具有对于两个氧化铝AlO包含个氧化钙CaO的二铝酸钙CA2的第结晶矿物学相和/或对于个氧化铝AlO和个二氧化硅SiO包含两个氧化钙CaO的铝硅酸二钙C2AS的第二结晶矿物学相。根据本发明，所述第和第二矿物学相作为整体在所述铝酸钙中的质量分数不小于80％。
