Exp 5 Bulk Density Civil Engineers PK

If the particles are of the same size, then it can be packed to a limited extent but when the smaller particles are added, the voids get filled with them and thus the bulk density increases. For a coarse aggregate, a higher bulk density means that there are few voids which are to be filled by the fine aggregate and cement.
