Tests for geometrical properties of aggregates - Determination of shell content. Percentage of shells in coarse aggregates PAS 15

Tests for geometrical properties of aggregates - Determination of shell content. Percentage of shells in coarse aggregates PAS 151 Scope 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 di Di where Di 63 mm and di 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 di Di where Dii 63 mm and di 4 mm.
