WebIn 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. WebConcrete with a low water-cementitious ratio (0.40 or lower) is more durable than concrete with a high water-cementitious ratio (0.50 or higher). Air-entrained concrete with a low water-cementitious ratio and an air content of 5 to 8 percent of properly distributed air voids will withstand a great number of cycles of freezing and thawing ...
