What is BS 812-111 - Determination of ten per cent fines value (TFV) of aggregates about?
BS 812 is the British Standard for testing aggregates. The main objective of the BS 812 series is to provide the best industry guidance to ensure construction materials contribute to the structural integrity of your civil engineering works.
BS 812-111 is the 111th part of the BS 812 series that 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.
Who is BS 812-111 - Determination of ten per cent fines value (TFV) of aggregates for?
BS 812-111 on the determination of ten per cent fines value (TFV) of aggregates is useful for:
- Manufacturers of aggregates
- Mineral materials and products manufacturers
- Cement and concrete industry
- Civil engineers
- Contractors
Why should you use BS 812-111 - Determination of ten per cent fines value (TFV) of aggregates?
TFV is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. The particular purpose that an aggregate is meant to serve requires the aggregate to have a particular strength.
In this regard, BS 812-111 provides the testing apparatus, sampling of aggregates and preparation of test specimens as well as includes test procedure to determine the TFV of aggregates.
As a result, if you are an aggregate manufacturer, complying with BS 812-111 can demonstrate the quality, performance, and dependability of your products, achieving the structural integrity required for building works.
Moreover, the main purpose of TFV is to assess the suitability of coarse aggregates for use on different types of roads.
