Packing Density

2021-8-2 · It also seems that the particle''s angularity has a strong influence on packing density: de Larrard (1999) reported that rounded aggregates give a packing density close to 0.60 while crushed aggregates packing gives values between 0.50 and 0.57. Such results suggest that packing density can be related to a ''roundness'' factor and some attempts to do this have been described in the literature …
