The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized
The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total weight of the sample expressed a s a percentage is defined as Aggregate Crushing Value. The apparatus is available in three size 75mm dia for 1/8” to ¼

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.
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 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 apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of:
This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%.
Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.
