Determination of Minimum Void Ratio of Crushed Rock Sand ...

 · Because the crushed rock sand has not undergone any weathering processes, it has a higher breakage potential than that of natural sand. This experimental investigation aims at developing a reliable method for the determination of the minimum void ratio ( e min ) of crushed rock sand using a vibrating table test.
