Bulk density of crushed stone
Crushed stone is a derivative of crushing large stones - gravel, boulders of different rocks. The ratio of volume to mass of bulk material is the density of crushed stone in working condition. This parameter affects the strength of the stones, it is taken into account when preparing concrete mixtures and choosing a fraction to create embankments and litter.
