HOW TO CLASSIFY AGGREGATES ACCORDING TO SIZE ...Jul 07, 2014· Partially Crushed Gravel or Stone– it is a product of the blending of the above two aggregate. According to size coarse aggregate is described as graded aggregate of its nominal size i.e. 40 mm, 20 mm, 16 mm and 12.5 mm etc. for example a graded aggregate of nominal size 20 mm means an aggregate most of which passes 20 mm IS sieve.
