Grading of Aggregates Aggregate Grading The

In grading of aggregates the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement Mix that occupies the least volume is the densest and will produce the best results
