Washing of Aggregates Influence on Aggregate Properties

The effect of washing on the performance of the aggregates in mortars was evaluated with a viscometer (Contec 4, ConTec Ltd.) suited for measurements on coarse particle suspensions, i.e., on suspensions with particle sizes up to approximately 16 mm.

Washed Aggregates BoDean

Washed aggregates are simply aggregate material that has undergone the wash process to remove dirt, or any other matter by applying a heavy force of water. More simply put, this is the process of washing clay, dirt and debris off of the rock once the aggregate has been mined.
