Aggregate Crushing Value Test -Determine Aggregate Crushing Strength
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.

Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.

The percentage mass of fines (passing a 2.80mm BS test sieve) formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than their crushing values.
