THE DETERMINATION OF THE 10 PER CENT FINES AGGREGATE CRUSHING VALUE 1 SCOPE The 10 per cent Fines Aggregate Crushing Value (10 % FACT) as defined hereunder is determined by measuring the load required to crush a prepared aggregate sample to give 10 per cent material passing a specified sieve after crushing. The procedure described in …
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. Read More++.

Aggregate 'Ten Percent Fine Value' (TPFV): The other way of representing the strength of aggregate is the 'ten percent fine value' (TPFV), that is basically the load needed for 10% fines. As compared to aggregate crushing value test this test is more reliable for representing the strength of aggregate.

determination of the ten per cent fines value (TFV) of aggregates which give a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two procedures are described, one in which the aggregate is tested in a dry condition and the other in a soaked condition.
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 ...
