WÄSSRIGE SUSPENSIONEN VON KIESELSÄURE UND DEREN VERWENDUNG IN MINERALISCHEN BINDEMITTEL |
摘要 |
An aqueous suspension is provided including a mixture of at least one aqueous suspension of precipitated silica and of at least one latex, in which the aqueous suspension of precipitated silica has a solids content of between 10 and 40% by weight, has a viscosity lower than 4x10-2 Pa s at a shear of 50 s-1 and, after centrifuging at 7500 revolutions per minute for 30 minutes, produces a supernatant containing more than 50% of the weight of the silica initially in suspension.This suspension can be employed in compositions based on an inorganic binder and in concrete compositions. |
