Jul 18, 2021 Aggregate crushing value = = (Weight of fraction passing through the 2.36 mm sieve) / (Weight of surface dry sample) = (W 2 x 100) / (W 1-W) Where W is the weight of empty cylinder. Result. The mean of the two results shall be reported to the nearest whole number as the “aggregate crushing value” of the size of the material tested.

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 for cement concrete road. The aggregate whose crushing value is less …

The Aggregate Crushing Value (ACV) Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.

The aggregate crushing value is defined, as a ratio of the weight of fines passing the specified IS sieve to the total weight of the sample expressed as a percentage. The aggregate crushing value is a value which indicates the ability of an aggregate to resist crushing.

BS 812: Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete and 40 on aggregates used in lean concrete. • For crushing values of over 25 to 30, the test is insensitive because the weaker material is crushed before the 400 kN load is reached and compacted in a manner that further crushing is reduced. For such materials, a ten percent fines value test is suggested by BS:812, Part 3.

Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. Fine aggregates are defined as those passing 2.36mm sieve. The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%).
