##### aggregate crushing value bypressive strenth

Aggregate Crushing Value By Compressive Strenth. Aggregate Crushing Value. Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV than Irregular or rounded aggregates.If we cut a core out of the same agg (Say in the quarry) and test for compressive strength will give a higher MPa value.

##### Does Recycled aggregate offer strength?

Strength of concrete using Construction Demolished waste ( may be called as recycled aggregates) depends on type of aggregates , size, shape , cement content and water cement ratio.

##### COMPRESSIVE STRENGTH OF RECYCLED AGGREGATE

5. Recycled Aggregate (RA) - used as coarse aggregate The recycled coarse aggregates were produced by crushing the waste concrete cubes at outer UTHM Material Laboratory that had compressive strength between 20 to 25 MPa. These waste cubes were broken into smaller pieces and crushed using a jaw crusher. Then the RA produced is sieved with
