Aggregates

Coarse aggregates are any particles greater than inch, but generally range between 3/8 and 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.
