The bulk density of an aggregate may be defined as the mass of the material in a given volume. It depends on how densely the aggregate is packed.

The other factors affecting the bulk density are the particle size & shape, the grading of the aggregate and moisture content.

• Bulk density of aggregate is generally expressed as kg/litre.
