Aggregate plays a vital role in providing strength to concrete. without aggregate, it remains mortar only. Bigger the size of aggregate, more strength it will provide. But aggregate size must be 5 mm bigger than the dia. of largest bar used in any element. Mostly used aggregate size is 20 mm. maximum.

Aggregate Crushing Value - engineeringcivil.com
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. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate
