Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load. It’s the percentage by weight of the crushed(finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the strength of the aggregate used in road construction. Aggregates with lower crushing value

In general, large size of aggregates used in the test results in higher aggregates crushing value. The relationship between the aggregate sizes and the crushing values will however vary with the type0'[specimens tested. When non-standard sizes of aggregates are usnd for the crushing test, (i.e. aggregate larger than 12.5 mm or smaller than 10 mm) the size of the cylinder, quantity of material ...

DETERMINATION OF AGGREGATE CRUSHING VALUE

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 apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) A

Aggregate crushing value test Step by Step Procedure ...

Aggregate Crushing Value (ACV) can be determined by using a simple formula: 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%. If it is more ...

Impact and Crushing Value - PCTE

The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. For durability and reliability, all parts of the apparatus are galvanized steel or powder coated, heat treated and ground prior to manufacturing. For ...

Aggregate Crushing value test procedure Civil4M

04/10/2020  The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components. The aggregates used for the surface course of pavements

Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. Fine aggregates are defined as those passing 2.36mm sieve. The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate ...
