Apr 13, 2020 · 4.) Flaky Aggregates – The aggregate is said to be flaky when the least dimension of aggregate is less than 3/5th (or 60%) of its mean dimension. Mean dimension is the average size through which the particles pass and the sieve size on which these are retained. For example, mean size of the particles passing through 20 mm sieve and retained on 16 mm sieve is (20+16)/2=18 mm.
