Sampling for Aggregate Crushing Value Test: For the Aggregate crushing value test, an aggregate sample passing through mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mould about kg of a sample of aggregate is sufficient.

Aug 11, 2020· 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%.

Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The " aggregate crushing value " give a relative measure of the resistance of

Advantages Aggregate Crushing Value Test Report. 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 conditions, and the strength of the aggregate used in road construction is expressed by numerical index .

The test aims at looking for the forces required to produce 10% of fine values ( weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.

Aggregate Crushing Value and Its Test Procedure: One of the test in which concrete material can fail is due to crushing under compressive stress. Aggregate crushing test is standardized by IS: 2386 partIV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through and retained on ...

aggregate crushing value test report result. Aggregate Crushing Value Test Procedure and Result “Aggregate 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.

This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test. Importance Impact Value Test: Generally, the majority of the aggregate test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.

May 05, 2010· Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
