Dec 19, 2019 If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

The aggregate crushing value ACV of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS
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 ...
Dec 15, 2017 Aggregate Impact Values, AIVs, below 10 are regarded as strong, and AIVs above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate
Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.
The aggregate crushing value ACV provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available 150 standard and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure. Cylinder, plunger and base plate are made from special alloy ...
