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 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41.
Tests have been carried out according to British Standard BS 812-1975 on non-standard and standard size aggregates to study the influence of aggregate size on mechanical properties. Dolerite, granite, limestone aggregates of different sizes have been tested. No basic relations have been found between elongation index, IE, and flakiness index, IF, and the different aggregate sizes.

This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.

For the BS 812-112 method, a small portion of 14–10-mm-sized coarse aggregate particles is confined in a steel pot and subjected to 15 blows by a small hammer in a standardised test rig, after which the ‘ aggregate impact value’ (AIV) is determined from the fine material generated, expressed as a percentage of the original weight of the ...

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.

Elongation index and flakiness index of coarse aggregate (BS 812 Part:1) Scope: The particle is considered as elongated if its length is more than 1.8 times the mean sieve size of the size fraction to which the particle belongs. Similarly, the particle is considered as flaky if its thickness is less than 0.6 ...
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 ...
