2006-7-1  Fig. 8 shows the variation of voids in mineral aggregates (VMA) with binder content for Mix I and Mix II. VMA increases with the binder content after having a minimum point. VMA is a direct function of air voids and effective binder. Higher level of compaction reduces the air voids, and hence the VMA reduces with the increase of the compactive ...
