The bulk density or unit weight of an aggregate is defined as the mass of the aggregate per unit volume. it is expressed in kg/liter. What is the value of Coarse Aggregate Density? Most of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m 3 (150-181 lb/ft 3 ).
