Ultra-fast setting cement based on amorphous calcium aluminate comprising a surface treatment
Disclosed is an ultra-fast setting cement composition including at least amorphous calcium aluminate including by weight, as compared to amorphous calcium aluminate total weight, (a) from 35 to 55% of calcium oxide CaO (C), (b) from 19 to 55% of alumina Al2O3 (A), the C/A molar ratio being higher than or equal to 1.5, preferably higher than or equal to 1.7, characterized in that amorphous calcium aluminate is coated with a surface treatment including an organic compound having at least two hydrophilic functions and one hydrophobic chain. Also disclosed is a method to produce the cement composition, as well as to uses thereof.
