APPLICATIONS OF AGGREGATE CRUSHING TEST: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indi es strong aggregates, as the crushed fraction is low. Thus the test cans be used to assess the suitability of aggregates with reference to the crushing strength for various types ...

Aug 11, 2020 The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
