Aggregates
Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.

How Are Aggregates Used in Concrete?
The proportions of coarse and fine aggregates you use in your concrete mix will depend on the aggregate characteristics, the placement method, and the desired finish. Fine Aggregates. The fineness of aggregates is measured using the fineness modulus (FM). The FM for fine aggregates should be within the range of 2.3 to 3.1.
