Define Crushing Value Of Concrete
X = Crushing value of concrete in N mm 2. The value of standard deviation will be lesser if the quality control at the site is excellent, and most of the test results will be approximately equal to the mean value. If quality control is unsatisfactory, then the test results will have much difference from the mean value.

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. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate.
