Aggregates for Concrete as per American Standards ASTM

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. In this article, we discuss []

5 Aggregate Production IN.gov

After primary crushing/reduction the resulting aggregate generally is placed in a large "surge" pile where the aggregate may be fed into the secondary operation whenever convenient. Care is always taken when building up and loading out surge piles, as this step may be a major source of segregation of material going to the secondary plant.
