Elongation index and flakiness index of coarse aggregate

Elongation index and flakiness index of coarse aggregate (BS 812 Part 1) Scope The particle is considered as elongated if its length is more than 1 8 times the mean sieve size of the size fraction to which the particle belongs Similarly the particle is considered as flaky if its thickness is less than 0 6

FLAKINESS SIEVES

Flakiness Sieves are used to determine particle size shape or geometrical characteristics of the aggregates Aggregate particles are considered as flaky when their thickness is less than 0 6 of their mean sieve size Aggregate to be classified is separated into seven sieve fractions from 6 3 to 63 mm and each fraction is examined separately
