All About bulk density and % of voids of fine aggregates

The percentage of voids in fine aggregates is a measure of the empty spaces or gaps between the particles. It is expressed as a percentage of the total volume of aggregates. The lower the percentage of voids, the higher the bulk density and vice versa. The % of voids of fine aggregates is influenced by the shape, size, and grading of the particles.

Aggregates for Concrete

Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
