In general, all mineral admixtures reduce bleeding of concrete. Admixtures with finer particle size and higher specific surface area are suitable for preparing high density and low permeability concrete. Increase in water demand due to addition of admixtures may be handled by the use of an effective superplasticizer. All these factors ...
