Bulk Density - an overview ScienceDirect Topics

Bulk density (or density in a mass) is the weight of the material including the intergranular air space in unit volume. This is determined with the help of the test weight apparatus (Fig. 13.12).The container comes in a litre or 500 ml capacity. The grains are allowed to fall into the container from a standard height at a standard flow rate through the funnel.

Bulk Density and Void Percentage Test for Aggregates -

The bulk density or unit weight is the weight per unit volume (mass per unit volume or density). Voids in unit volume of aggregate are the space between particles in an aggregate mass not occupied by solid minerals. The bulk density values determined based on this test can be used for many methods of selecting proportions for concrete mixtures.

Bulk Density - Measurement Fact Sheets soilquality.au

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit
