description The invention relates to an ultra-fast setting cement composition comprising at least amorphous calcium aluminate comprising by weight relative to the total weight of the amorphous calcium aluminate: (a) 35 to 55 % calcium oxide CaO (C); (b) 19 to 55 % alumina AI2O3 (A), the molar ratio C/A being greater than or equal to 1.5; and (c) 0 to 10 % silica SiO2, characterized in that the amorphous calcium aluminate comprises: (d) 5 to 16 % iron oxide Fe2O3. The invention also relates to a method of producing the cement composition and to its uses.
