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 ...
Oct 03, 2019 Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. 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.
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.
Chapter 7 Standard Test Procedures Tests For Aggregates And Bricks MAY 2001 Page 7.35 7.7.1.9 Results. Calculate the mean of the two values determined to the nearest whole number. Report the mean as the Aggregate Crushing Value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four ...

The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined compression test of recycled CDW.
In crushing test, the aggregate used is passing through mm sieve and retained on mm. a 20mm, 16mm b 16mm, 12.5mm c 12.5mm, 10mm d 10mm, 4.75mm. The aggregate with crushing value below 30 is suitable for withstanding heavy load a True b False. Aggregate crushing value provides the relative measure of resistance to.
Aggregate crushing value test is done the find the actual crushing value of aggregate. We Need to carry out this test, 1.To find out how much resistance does the aggregate has against the surface abrasion under traffic. 2.To find out how much resistance does the aggregate can withstand under the roller during construction. 3.To determine the strength of coarse aggregate and suitability of the aggregate for construction. How to perform Aggregate crushing value test
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 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.
