摘要
A silica sol mixture is described comprising a first silica sol having a broad particle size distribution, the relative standard deviation of which being at least about 30% by numbers, and a second silica sol having a narrow particle size distribution having a relative standard deviation lower than about 15% by numbers. Also described is a method for preparing a silica sol mixture and uses thereof, a concrete composition comprising a silica sol mixture and a method for preparing that composition.
