Coarse aggregates are the particles that retain on 4.3: Materials: Sand, surki, stone screenings, burnt clays, cinders, fly ash, etc are used as fine aggregate in concrete.Brick chips (broken bricks), stone chips (broken stones), gravels, pebbles, clinkers, cinders etc.Are used as coarse aggregate in concrete.
Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate.Most natural sands and gravel from riverbeds or seashores are smooth and rounded and are excellent aggregates.Crushed stone produces much more angular and elongated aggregates, which have a higher surface-to-volume ratio, better .
Crushed stone, sand, and gravel can all be used as drainage aggregates.Drainage aggregates are either natural or processed, and coarse or fine.Coarse aggregate is typically larger than 5 mm in diameter, while fine aggregates are less than 5 mm.Road and patio base layers can benefit from using both crushed stone and gravel.

Increase in aggregate size results in a decrease in the compressive strength of concrete.Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio.
