Lightweight aggregate: Lightweight aggregate is often defined as any aggregate with a dry loose bulk density of less than 1200 kg/m 3. Lightweight aggregates are used to produce lower density concretes, which are advantageous in reducing the self-weight of structures and also have better thermal insulation than normal weight concrete.

The density of sand (fine aggregate) is ranging between 1450-2082 kg/m3 depending on different conditions like wet, dry, loose, dry-packed, and wet packed. What is Bulk Density of Aggregate? The Unit weight or bulk density of aggregate is the mass or weight of the aggregate required to fill a container of a specified unit volume.

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.

This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

If the particles are homogeneous in chemical composition and entirely smaller than 100 microns, the best way to break up the compaction and fill the container is by hand tapping the powder through a ~2-millimeter (10-mesh) sieve above the container so that the powder disperses and "rains" gently into the container.
