More Details· 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

More Details· Aggregate Crushing Value. 1.0 Introduction. The principal mechanical properties required in stones are satisfactory resistance to crushing under the roller during construction and adequate resistance to surface abrasion under traffic. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads.

More Details· Significance : The aggregate crushing value gives relative measure of the resistance to crush under a gradually applied compressive load. Definition : It is defined as the ratio of the weight of fines to the total sample weight expressed as a percent when tested as per the IS procedure.
