Aggregates is a general term for rocks and minerals used in a variety of industries for a range of purposes. Aggregate is classified by particle size and consistency. There are two basic types: sand and gravel (sometimes called natural stone)and crushed stone. More recently a third type of aggregate has emerged: recycled concrete aggregate, which is produced by crushing concrete reclaimed from demolished highways, buildings and other structures.
