AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.

Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing …
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS
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 other size fractions, there is another recommended method.
aggregate crusing velue. Aggregate Crushing Value (ACV)-Testing Procedure. Definition of ACV: Aggregate Crushing Value (ACV) gives an relative measure how the aggregate act under an gradually acting compressive load. Sieve Size: ACV is applicable for aggregates passing 14.0 mm sieve and retained on 10.00 mm sieve.

The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per cent fines value described in BS 812-111 is applicable. Standard Number: BS 812-110:1990: Title: Testing aggregates.
Aggregate Crushing Value Test Procedure And. 2020-6-22Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load In situations when aggregate value 30 or higher the result may be a mistake and in such cases the ten percent fines value should be determined and used instead.
It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface.
