Water reducers for the high alumina cement-silica fume system

High early strength mortars or concretes can be produced with high alumina cement. However, at later ages, particularly above 20 C, strength loss occurs due to transformation of hexagonal hydrates into the cubic form. Silica fume is capable of hindering or blocking this transformation.
