Aggregates for Concrete as per American Standards - ASTM [PDF]

The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. The aggregates may be natural, manufactured, or recycled. The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate.ARKANSAS RESOURCES FOR CRUSHED-STONE .For construction applications, stone used in aggregates must be sufficiently durable to meet the rigors placed on the aggregate by its intended use.
