Construction aggregates: evaluation and specification
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. An ACV greater than 35% indicates that aggregate is too weak for most construction uses. A variation is the Ten Per Cent Fines Value (TFV) which is expressed ...

Ten Percent Fines Value
by Civil Yard · Published December 24, 2022 · Updated December 24, 2022. The ten percent fines value is a measure of an aggregate's resistance to crushing, and it is applicable to all aggregates. This test is quite similar to the aggregate crushing test, which measures the amount of fines material crushed as a percentage of the initial mass.
