Testing aggregates -- Methods for determination of ten per cent fines value (TFV)
This Part of BS 812 describes methods for the determination of the ten per cent fines value (TFV) of aggregates which give a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
Two procedures are described, one in which the aggregate is tested in a dry condition and the other in a soaked condition.
The methods are applicable to both weak and strong aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, a recommended method is described in appendix A.
