Ten Percent Fines Value
The 10 % Fines Value (TFV) is determined by measuring the load required to crush a prepared aggregate sample to give 10 % material passing a specified sieve after crushing. The test is also known as the 10% Fines Aggregate Crushing Test - 10 % FACT. The test can be performed in both a dry condition and in a soaked condit-ion.
