An aqueous suspension including a mixture of at least one aqueous precipitated silica suspension and at least one latex, wherein said aqueous precipitated silica suspension has a dry matter content of 10-40 wt % and a viscosity of less than 4.10 Pa.s for a shear of 50 s<-1>, and produces, after centrifuging at 7500 rpm for 30 minutes, a supernatant containing more than 50 % of the weight of the silica originally in the suspension. Said suspension may be used in inorganic binder compositions and concrete compositions. |
