The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve.
The aggregate crushing value gives a relative measure of the resistance of aggregate in bulk to crushing under a gradually applied compressive load. Crushing value is defined as the ratio of finess passing a standard sieve produced by crushing under standard condition to the weight of coarse aggregate expressed as a percentage.

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%). 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.

Procedure of testing Aggregate Crushing Value (ACV): 1. Make a sieve analysis and get sufficient amount of aggregate by using 14.0 mm passing sieve and 10.00 mm retained sieve. 2. After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm. 3.
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.
The "aggregate crushing value" gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The standard aggregate crushing test is made on aggregate passing a 12.5mm I.S. sieve and retained on 10mm I.S. sieve.

Exp 4 Aggregate Impact Value. Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) ... Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties.
The aggregate crushing value (ACV) provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. OBJECTIVE: For determination of the aggregate crushing value of coarse aggregate, of size ranging from 10 mm to 12.5 mm.
We are satisfied with this value since the percentage of aggregate crushing value is less than the standard value of 35%. the aggregate crushing value that we obtained from the test is about 18. CONCLUSION In conclusion. we recommend that this type of aggregate is suitable use to construct the highway road and can withstand heavy traffic load.
