    Jul 23, 2020· Importance Of Aggregate Gradation. When a range of size is used, smaller particles can pack between the larger particles, thereby decreasing (Vv) which is the volume of voids and hence lowering paste requirements. Aggregate gradation is an important property in the selection of aggregates from particular sources for use in concrete.
