What is BS EN 933-4 - Determination of the shape index of coarse aggregates about?
BS EN 933 is a European Standard on tests for geometrical properties of aggregates. The main aim of the BS EN 933 series is to provide the best industry guidance to ensure construction materials contribute to the structural integrity of civil engineering works.
BS EN 933-4 is the fourth part of the BS EN 933 series that describes the reference method used for type testing and in cases of dispute, for the determination of the shape index of coarse aggregates. For other purposes, in particular, factory production control, other methods may be used provided an appropriate working relationship with the reference method has been established.
The test method specified in BS EN 933-4 is applicable to particle size fractions di/Di where Di ≤ 63 mm and di ≥ 4 mm.
