Abstract (en)
[origin: WO2015173526A1] 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); and (b) 19 to 55 % alumina AI2O3 (A), the molar ratio C/A being greater than or equal to 1.5, and preferably greater than or equal to 1.7. The invention is characterized in that the amorphous calcium aluminate is coated with a surface treatment comprising an organic compound comprising at least two hydrophilic functions and a hydrophobic chain. The invention also relates to a method for producing the cement composition and to its uses.
