Standard Of Crushing Value Of Coarse Aggregates For
To complicate matters , 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.An aggregate which passes the 0.063mm sieve) Aggregate for applications in mortar are divided into five categories in terms of its fines content. In ‘Category 4’, a fines content of 30 (maximum) is permitted for use with crushed rock aggregate in mortars. The maximum value of fines content specified under Category 3, which excludes.
