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.
