  The bulk density of aggregates is generally expressed as

  2024329 · It depends on the properties of the aggregates. Note: The bulk density of aggregates is generally expressed as kg/cum. Lower Bulk Density → Lower weight → More voids. Higher Bulk Density → Higher Weight → Less voids. Factors affecting the Bulk density of aggregates: 1. Packing of aggregate i.e. loosely packed aggregates or well ...

  Properties Of Aggregates- Physical Properties, Chemical

  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.
