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.

Aggregate Crushing Value | sarat

Calculations: Aggregate Crushing Value = (B/A) * 100 % * The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. * Aggregate crushing value < 45% for aggregates used for concrete for non wearing surfaces and <25% for wearing surfaces like runways and roadways.

7 Lab Test on Aggregate Should Satisfy for Use in 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.
