|And For Elongated Particles, their Maximum dimension should be larger than 1.8 times of mean size.|

|In other words we can say that an aggregate is said to be flaky if its least dimension is less than 0.6 times of mean dimension.|

|1. Flaky Particles: The particles whose least dimension is less than 0.6 times the mean size dimensions.
2. Elongated particles: The particles whose greatest dimension is greater than 1.8 times the mean size dimension.
3. Mean size of aggregates: Mean size of aggregates is defined as the mean of two seive sizes, between which the particle is retained i.e. Mean size = (Passing sieve size + Retaining sieve size)/2.
