Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger

Determinationof The Ten Percent Fines Value
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

Why is a crushing test important? –
The ‘aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Due to this reason, the aggregates used in road construction must be strong enough to withstand crushing under roller and traffic

Crushing Value of Aggregate
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: IS 2386 (Part 4):1963)

An investigation of the relation between ten per cent
Ten per cent fines load and ACV tests are two well accepted tests for assessing the mechanical properties of aggregates. While the load producing ten per cent fines is determined in the former test, the amount of fines produced under 40 ton load is given as ACV in the latter test. Both tests are standardised in the U.K. and carried out in the same way, on the approximately same

Feb 08, 2012 Impact, 10% Fines & Crushing Tests If the percentage fines exceeds 30, the result may be anomalous as the broken pieces of aggregate will tend to fill the voids and prevent further crushing. In this case, the Ten Percent Fines Test is more appropriate. Some countries, e.g., Australia and New Zealand, only use the latter test
