Constituent Materials of Concrete - InterNACHI

Aggregates for concrete are generally divided into two categories: fine and coarse. Fine aggregates are generally natural sand or crushed stone, with most particles passing through a 3/8-inch (9.5-mm) sieve. Coarse aggregates generally range between 3/8- to 1-1/2 inches (9.5 mm to 37.5 mm) in diameter.
