Shape, Size - Coarse Aggregates

In such, many properties of aggregate depend on the properties of the parent rock itself. Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is ...

European Aggregate Sizes - Northstone Materials

To complicate matters more, for fine and all-in 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, i.e., 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.
