Crushed Concrete Aggregates - Properties and Uses of ...
Influence of Recycled Aggregate on Concrete Properties 1. Concrete Strength Reductions By and large, strength of concrete produced from crushed concrete aggregate is lower than concrete made using natural aggregate. Strength reduction of concrete produced from recycled coarse aggregate and natural fine aggregate ranges from 5 to 24%.
Aggregates for Concrete
More performance tests are also used to test aggregates in concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special
What is Crushed Aggregate? (with pictures)
Crushed aggregate may be combined with other materials to produce concrete. After being processed in the impact crusher, the aggregate is screened for sizing. This process might be handled in a screen shaker or during the washing process in an aggregate washer. If the aggregate is sufficiently crushed, it is transported to the storage area.
