importance of size of coarse aggregate

the coarse aggregates should be properly graded, and the gradation becomes more and more important as we increase the maximum size of coarse aggregate because of greater voids, which needs to be filled to attain the desired compressive strength as void fraction increases on increasing the size of aggregates
