2.4. Bulk density of aggregate The bulk density of the recycled aggregate, due to a higher porosity of mortar layer, has a lower value than the bulk density of natural aggregates and their mutual difference decreases if recycling is con-ducted by an advanced technology, which can remo-ve a significant portion of the old cement mortar.
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.
Bulk Density: The bulk density or unit weight of an aggregate gives valuable information's regarding the shape and grading of the aggregate. Specific gravity the angular aggregates show a lower bulk density. The bulk density of aggregate is measured by filling a container of know volume in a standard manner and weighing it.
Step 7 -Estimation of coarse aggregate content • The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given in Table. • The value from the table multiplied by oven dried weight of coarse aggregate required per cubic foot of concrete. • Volume of coarse aggregate = 0.63 x 27 (ft3/yd 3) = 17.01 (ft3/yd 3)

density, shape, or volume. Bulk density can also be estimated from field measurements using a nuclear density gauge (see SOP 61) or measured with a sand cone (see SOP 65) or sand replacement (see SOP 70) test. Bulk density measurements of the same material with all three methods will not necessarily yield the same results because each method

Bulk Density and Voids. Bulk density – mass of aggregate in unit volume. Includes voids. 30% - 45% voids in coarse aggregates. 40% - 50% voids in fine aggregates. Angularity increases voids. The bulk density or unit weight of an aggregate is the mass or weight of the aggregate required to fill a container of a specified unit volume.
