All About bulk density and % of voids of fine aggregates
Bulk density of fine aggregates, also known as bulk unit weight, is the weight of the aggregate material in a given volume. It is usually expressed in kilograms per cubic meter (kg/m3) or pounds per cubic foot (lb/ft3). The bulk density is an important parameter in determining the suitability of aggregates for various construction applications.
