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. 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. 2.Apparatus Required.

Sieve Analysis Test Procedure And Calculation

Take a 1kg fine aggregate test sample. Arrange the IS sive in descending 10mm, 4.75mm, 2.36mm, 1.18mm, 600 microns, 300 microns, 150 microns and 75 microns. Now fill the sample to the highest sieve and sieve well for up to 10 minutes. After completion of sieving, then weigh the aggregates retained in each sieve & note it down.

Aggregate Crushing value test procedure | Civil4M

10/04 · 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.
