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.AGGREGATE DATA SHEET,QUARRY AGGREGATE DATA SHEET Basic Information Type of Processing Quarry Location Huntly, Waikato Type of Rock Greywacke Type of Aggregate TNZ M/4 AP40 Three stage Scalping, Crushing, Washing and Screening or Pugmill Blend of High Quality Fines and Crushed AP40.

This specification is written as a provincial-oriented specification. Provincial-oriented specifications are developed to reflect the,5 Aggregate Specifications and Requirements,Physical quality requirements are all specification provisions other than those dealing with gradation or usage requirements. These requirements can be divided into five distinct groups as follows: 1) Absorption; 2) Abrasion resistance; 3) Soundness; 4) Restrictions on deleterious constituents; and 5) Special requirements.
