Objectiveobjective Aggregate Crushing Value Test

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 1.It is recommended that the crushing value of.

    Aggregate Crushing Value Test Procedure And Result

    Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa We) W2= Weigh of aggregates passing through 2.36mm IS sieve.The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.

Aggregates are a very important component of concrete, so the quality really matters when it comes to aggregates.Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger.
