Bulk Density - Measurement | Fact Sheets | soilquality.org.au

If soil has >10 % gravel or the stones are >2 cm conventional bulk density readings will be inaccurate, as most coarse fragments have bulk densities of 2.2–3.0 g/cm 3 (McKenzie et al., 2002). This is important to recognise when using bulk density measurements to calculate nutrient levels on an area basis, as an over-estimation will occur.

Determination of bulk density of aggregates – Seismic

For the determination of the loose bulk density, fill the container with the aggregate material by means of a shovel and level its top surface. Discharge the aggregate from height not greater than 2 inch. Weigh the container filled with the aggregate and note down its reading. Then the loose bulk density of the aggregate material can be computed by using the relation; For the determination of the compacted bulk density,

Level the surface of the aggregate using the tamping rod as a straightedge. Then weight the container with sample (M₃) and determine the net weight of the aggregate in the measure (M₃−M₁), which is called loose weight. Calculate the bulk density of sample aggregate in kilograms per litre (the formula is given below in calculations).
