Determination of bulk density of aggregates – Seismic ...

Discharge the aggregate from height not greater than 2 inch. Weigh the container filled with the aggregate and note down its reading. Then the loose bulk density of the aggregate material can be computed by using the relation; For the determination of the compacted bulk density, the only difference is in filling the container. In this case, the ...

Bulk Density of Aggregates - Civil Snapshot

Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense compacted aggregates. In case, if the specific gravity of a material is known, then it …

1. Scope. 1.1 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.

After that, weight the aggregate mass that is inside the container and divide it by the volume of the container. This will give you the bulk density of the loose aggregates. Compacted bulk density. Compacted bulk density can be determined by filling the container in three layers and tamped each layer with a 16mm diameter rounded nosed rod.

1.Introduction. An increase in bulk density of soil resulting from loads applied for short periods is referred to as compaction (Kayombo and Lal, 1993; McAfee et al., 1989).Compaction of a soil may adversely affect air and water movement, seedling emergence and root penetration (Chen and Weil, 2010).Primary plant roots are usually larger than many of the pore spaces available to them ...
