BS EN 933-7:1998

This standard BS EN 933-7:1998 Tests for geometrical properties of aggregates is classified in these ICS categories:

• 91.100.15 Mineral materials and products

This European Standard specifies a method for the determination of shell content of coarse aggregates. It applies to gravel or mixed aggregate containing gravel.

The test method specified in this part of this European Standard is applicable to particle size fractions d_i/D_i where D_i ≤ 63 mm and d_i ≥ 4 mm.

NOTE For aggregate sizes with D > 63 mm and/or d < 4 mm the test may be carried out on particle size fractions d_i/D_i where D_i ≤ 63 mm and d_i ≥ 4 mm.

Specifies the method for determining the shell content of coarse aggregates and is applicable to gravel or mixed aggregate containing gravel.
