Ten per cent fines value (TFV) — Material Testing Expert
Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample. Normally, the percentage of fines should fall between 7.5 and 12.5. If it falls outside this range, conduct a new test at a load adjusted to bring the percentage of fines within the range of 7.5 to 12.5.

In general, LWA have lower crushing strength than NWA, because of its high porosity nature. Although many researchers did not present the crushing strength of the used LWA in their studies, some have presented it in the form of crushing strength, or aggregate crushing value (ACV), or aggregate impact value (AIV).
