The requirements of AS 2758.1 - 2009

2018-10-11  Particle Density (Clause 7.1) and Water Absorption (Clause 7.3) The particle density test is performed by taking a sample of aggregate and determining its mass by displacing a mass of water. The result is the ratio of the density of the aggregate to the density of water. The appropriate test method depends on the size of the aggregate being tested.
