Aggregate definition and Shape, Types, Properties Aggregate definition. Aggregates are the major ingredients of concrete. Aggregates are derived from rocks. They are broadly divided into two categories i.e. fine aggregate and coarse aggregate. Their properties are depended on the mineralogical composition of the rock. Crushed rocks are used as coarse aggregates are river sand is used as fine aggregates.

Difference Between Fine and Coarse Aggregate - Civil Engineering

Fine aggregates are the particles that pass through 4.75 mm sieve and retain on 0.075 mm sieve. Coarse aggregates are the particles that retain on 4.75 mm sieve. Sand, surki, stone screenings, burnt clays, cinders, fly ash, etc are used as fine aggregate in concrete.

combined gradation of aggregates pdf definition psychology

In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.

types of coarse aggregate definition chemistry

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. 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.
