Change Mix Design according to Coarse Aggregates – Civil ...Higher the surface area, greater is the water demand to coat the particles and generate workability. Smaller maximum size of coarse aggregate will require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix. Hence 40 mm down coarse aggregate will require much less water than 20 mm down aggregate.concrete mix design with coarse aggregate of 20 to 5mmCoarse aggregate were 12.5mm and 20mm crushed granite stones from a local quarry (CA12.5 and ...
