There are two types of bulk density of coarse aggregate – loose bulk density and compacted bulk density. 1. Loose Bulk Density: Loose bulk density is also known as uncompacted bulk density or loosely packed bulk density. It is the density of coarse aggregate when it is poured loosely in a container without tapping.

The bulk density measures the volume that the graded aggregate will occupy in concrete, including the solid aggregate particles and the voids between them. Since the weight of the aggregate is dependent on the moisture content of the aggregate, a constant moisture content is required. This is achieved by using OD aggregate.

279 Views. Bulk density refers to the mass of aggregate particles that would fill a unit volume. The concept of bulk density originates from the inability to pack aggregate particles in a manner that completely eliminates void spaces. Hence, the term bulk refers to the volume that encompasses both the aggregates and the voids. This measurement is crucial when aggregates are batched …

4) Bulk density. Bulk density or also called unit weight or unit mass is the density of the aggregate at a certain degree of compaction. It is numerically equivalent to the specific gravity of the aggregate. It is measured in kg/m3 in the construction field. Bulk density can be used to convert weight batches to volume batches.
