This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the 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.

Read MoreThe ten Percent Value Test is a test conducted on aggregates to measure their resistance to gradually applied loads. Aggregates used in construction should be strong enough to resist crushing under loading conditions. If the aggregates are weak, the integrity of the structure may be adversely affected.

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 than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used

getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: 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.
