Gap-Graded Aggregate And There Advantages - …

The size of voids existing between a particular size of aggregate is too small to accommodate the very next lower size. However, the presence of such a fraction may prevent compaction of the large aggregate to their maximum density. The voids may accommodate the size of aggregate which is 2 to 3 sizes lower than the particular size of aggregate. In the case of the gap-graded mix, the fine ...
