  • Sieve analysis of Aggregates of Grading for Granular Sub

    A sieve analysis (or gradation test) is a practice or procedure used to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass

    To complicate matters more, for fine and allin aggregate, where D <= 8mm, the standard requires producers to declare a "typical grading", which, where required, must be within a given Tolerance Category designated according to a set ± value on the D/2 sieve, ie, G TC 10, G TC 20 or G TC NR (no requirement) A typical quarry dust could be designated 0/4 G A 85 G TC 20
