size of aggregate divides coarse from fine aggregate

Concrete Aggregates

Fine aggregates contain particles in the size range 75 m 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 kg/m3 unit weight.

Function and Importance of Aggregate in Concrete

21/11/2016• Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm; typically, fine aggregates contain particles in the size range 75 m to 4.75 mm, and coarse aggregates from 4.75 to about 50 mm, except for mass concrete which may contain particles up to 150 mm.
