Different Types & Sizes of Aggregate for Concrete ...
Aggregate may be natural, manufactured or recycled. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.
