The bulk density of aggregate is an important factor that determines the volume occupied by the aggregates in a given concrete mixture. The bulk density of aggregate is typically measured in kilogram per cubic meter (kg/m^3) or pounds per cubic foot (lb/ft^3). It is calculated by dividing the weight of the aggregate by its volume.
