The FACT value is measured by crushing the aggregate sample and determining the force required to produce 10% fines, which are particles that pass through a 2,360 micrometer sieve. The test can be performed in either dry or wet conditions.

 — The result of this method is the 10% Fines Value (TFV), which is also a measure of the resistance of an aggregate to crushing under a gradually applied compressive load with the difference that the upper limit of …

The ten per cent fines load and the aggregate crushing value (ACV) tests are two well known and accepted aggregate tests for assessing the mechanical properties

a uniform rate to reach 400 kN in 10 minutes. The mea-sure of fragmentation is called Aggregate Crushing Value (ACV). The BS 812-111 introduces a very similar aggre-gate testing method to the Crushing Test. The result of this method is the Ten Percent Fines Value (TFV) which is also a measure of the resistance of an aggregate to crush-

 — The 10% fines value is a metric that gauges the ability of aggregates to withstand crushing under loading, and it is applicable to both weak and strong aggregates. Fine aggregates are those that pass through a 2.36mm sieve.

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 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.

 — 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.

 — The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined compression test of recycled...

Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing 2.36 mm is the ACV (mean value of two tests). The higher the value the weaker the aggregate.
