To compli e 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 egory designated according to a set & 77; value on the D/2 sieve, i.e., G TC 0, G TC 20 or G TC NR no requirement . A typical quarry dust could be designated 0/4 G A 85 G TC 20.
In case standard size aggregate i.e., aggregate particles passing 2.5 mm sieve and retained on 0 mm sieve is not available, then available aggregate upto 25 mm size can be tested. In this case material should be sieved on sieves shown in Table 4.7. For measuring the sample, cylinder of .5 cm diameter and 8 cm height may be used.
