13.04.2020The aggregate sample must pass through a 14mm sieve and should retain on 10mm sieve. The test limits the ACV value of sample to be less than 30. In case the value exceeds 30, Ten Percent Fines Value (TFV) Test should be carried out on the sample. This is because the test is likely to give misleading results for weak aggregates.
