Concrete Aggregates Function Properties

Fine aggregates contain particles in the size range 75 µm to mm and coarse aggregates from 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

Sieve analysis Wikipedia

A sieve analysis or gradation test is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution also called gradation of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass
