Apparatus For Weighing The Aggregates
Sieve Analysis Of Coarse And Fine Aggregates ...
· Fine Aggregates: They are the aggregate particles that pass sieve #4 but retain on sieve #200. Fine aggregates include a wide range of particle sizes. Specifically talking about sands, the grainsize distribution further classifies sand into coarse sand, medium sand, and fine sand.
