what is dry loose density of diffent types of soils, murrum, soft rock and hard rock

what is the dry loose density of types of soils, murrum, soft rock and hard rock. using this data we can calculate volume by weighing dumper with load and empty dumper and netweight.this is useful record qtty n daily basis.

 

[Dnyan Deshmukh]

Dry loose bulk density is measure of density in which we check its loose weight (not compacted) in known volume.

Loose weight of any material per volume depends mostly on the shape and size of particles. closely packed materials do show higher density.

Aggregates - Are not closely pack and has voids in it - lead to lower densities.
Crush sand - Closely pack various sizes exhibits higher density.

Calculation of DLBD is very easy, you need to fill the material without compacting in known volume box / container and need to record its weight.

Weight divided by volume will give you its DLBD.
