The FAA test estimates fine aggregate angularity by measuring the loose uncompacted void content of a fine aggregate sample. ... Typical test values range from 38 to 52 percent voids. Crushed materials typically range from 43 to 52 percent voids and natural (uncrushed) sands typically range from 38 to 46 percent voids.
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.
