Aggregate production: Fines generation during rock crushing - EGELKeywords: Crushed stone; Cubicity; Sand; Crushing; Aggregates; Fracture modes; Mineralogy; Fines. 1. Introduction. The absence of natural aggregate at cost-effective transportation distances has prompted extensive use of manufactured aggregates. The US aggregate industry produces ∼1.1 billion tons of crushed stone.Aggregates for Concrete - Civil Engineeringnatural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed stone is produced by crushing quarry rock, boul- ders, cobbles, or large-size gravel.
