Implementation of a Fine Aggregate Angularity Test

Fine aggregates flow freely into a 1 OO-mL copper cylinder. By knowing the bulk specific gravity of the fine aggregate, G''b'' and the weight of fine aggregate in the cylinder of known volume, the uncompacted void content can be calculated. Very angular fine aggregates will have high uncompacted voids, and more rounded fine aggregates will have ...

Concrete Aggregates

Fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain particles up to 150 mm. Most natural mineral aggregates, such as sand and gravel, have a bulk density of 1520 to 1680 kg/cum and produce normal-weight concrete with approximately 2400 ...
