- | Aggregate Aggregate Crushing Value Meaning

If the aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate Whereas if the crushing value is 35 or above it would normally be considered as weak aggregate After performing the test the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
