- Coarse aggregates are particulates that are greater than 4.75mm. The usual range employed is between 9.5mm and 37.5mm in diameter. - Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size 40mm is more common in mass .

The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm and the coarse aggregate is a gravel that has been crushed washed and sieved so that the particles vary from 5 to 50 mm in size.The fine and coarse aggregate is delivered separately. As they need to be sieved a prepared mixture of fine and coarse aggregate is more expensive than the .

Crushed aggregate is produced by crushing quarry rock boulders cobbles or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases soil-cement and in new concrete. After harvesting aggregate is processed crushed screened and washed to obtain proper cleanliness and gradation.
