Sep 05, 2018 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. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. 51.
TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41.

Dec 19, 2019 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.
