This test is repeated once or twice and the average crushing value of the aggregate is determined. 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
Sampling for Aggregate Crushing Value Test For the Aggregate crushing value test an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 C to 110 C then cooled to room temperature
Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions
The aggregate crushing value test result should not be more than 30 for the concrete used for roads and pavements and in case of other structures it may be permitted up to 45. c Standard Guidelines for Crushing Test Followings are the standard guidelines for the crushing test on aggregates
This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test. Importance of Impact Value Test Generally the majority of the aggregate test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life

Sep 12 2015 Crushing Test Fig-1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS 2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied
While aggregate crushing value of above 35 would be considered as weak aggregates. According to Uche and Muhammad 2011 ACV of a concrete aggregate should not exceed 30
