What is BS 812-110 - Determination of aggregate crushing value (ACV) 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 812-110 is the 110th part of the BS 812 series that describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
The method is applicable to 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.
Note: The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases, the method for ten per cent fines value described in BS 812-111 is applicable.
Who is BS 812-110 - Determination of aggregate crushing value (ACV) for?
BS 812-110 on the determination of aggregate crushing value (ACV) is useful for:
- Manufacturers of aggregates
- Mineral materials and products manufacturers
- Cement and concrete industry
- Civil engineers
- Contractors
Why should you use BS 812-110 - Determination of aggregate crushing value (ACV)?
ACV is a numerical index of the strength of the aggregates, and it is used in the construction of roads and pavements. The crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance. The aggregates used in roads and pavement construction must be strong enough to withstand crushing under rollers and traffic.
In this regard, BS 812-110 provides the testing apparatus, sampling of aggregates and preparation of test specimens as well as includes test procedure to determine ACV.
As a result, if you are an aggregate manufacturer, complying with BS 812-110 can demonstrate the quality, performance, and dependability of your products, achieving the structural integrity required for building works.
Furthermore, the primary goal of ACV is to evaluate the viability of coarse aggregates for usage in various types of roadways.
