Importance of aggregate grading - Concrete Society. Ideally coarse and fine aggregate should be graded in such a way as to minimise the voidage.

Importance in terms of Workability. A workable concrete can be achieved by adding more water, but as we know the more water present in concrete the poor strength it gives. The most efficient way to achieve workable of concrete is by adopting a good gradation of aggregate. Also aggregate comprises 85% of the volume of concrete.

Results are expressed as mass per volume. For example, a given crushed limestone could weigh 93 lbs./ft.3. By knowing the DRUW of a coarse aggregate, the maximum nominal aggregate size and the fineness modulus of the fine aggregate, the weight of the coarse aggregate needed per cubic yard of concrete mix can be estimated.
