Each Size Group Of Coarse Aggregate

Flat and Elongated Particles  Pavement Interactive
Aggregates are coarse particulate rocklike material consisting of a collection of particles ranging in size from < 0.1 mm to > 50 mm. It includes gravel, crushed rock, sand, recycled concrete, slag, and synthetic aggregate. Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydrauliccement concrete, or iron blast .

Different Types & Sizes of Aggregate for Concrete .
Aug 11, 2018 · When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete.
