ScopeThis Part of BS812 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 test sieve and retained on a mm test sieve....
Aggregate Crushing Value Test, Crushing Value Test of Aggregate .
· The aggregate crushing value test evaluates the ability of the aggregates used in road or pavement construction to withstand the stresses induced by moving vehicles in the form of crushing. With this, the aggregates should also provide sufficient resistance to crushing under the roller during construction work and under rigid tyre rims of heavily loaded animals or men ....

aggregate crushing value of coarse aggregate. NOTE 1 The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre gate of 'aggregate crushing value' 30 or higher, the result may be anomalous, and in...
Pavement materials: Aggregates
Then crushed aggregates are then sieved through mm sieve and weight of passing material (W2) is expressed as percentage of the weight of the total sample (W1) which is the aggregate crushing value. Aggregate crushing value = W1 W2 100 A value less than 10 signi es an exceptionally strong aggregate while above 35 would normally be regarded as...

The aggregates which may be used in concrete must be free from silt, clay, and other marine impurities. 12. Crushing value of aggregate. Determination of the crushing value of an aggregate is helpful to find the compressive strength of the aggregate, whether it is suitable for the concrete work or not....
Aggregate Crushing Value | sarat
· Aggregates used in the construction, should be strong enough to resist crushing. If the aggregates are weak, the stability of the structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied ....
