How Coarse Aggregate Affects Mix Design of Concrete?

17/08/2019  Smaller maximum size of coarse aggregate would require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix. So, for the same workability, 40mm down aggregate would have lower water/cement ratio, thus higher strength when compared to 20mm down aggregate. Because of its lower water demand, advantage of higher maximum size of coarse aggregate
