    Aggregate crushing value test 10 fines value test Mechanical Properties of Aggregates Aggregate Crushing Value Test Discussion • There is no explicit relation between the aggregate crushing value and its compressive strength but in general the crushing value is greater for a lower compressive strength BS 812 Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete.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.
