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

The Flakiness Index of aggregates is the percentage by weight of particles whose least dimension (thickness) is less than three- fifths (0.6times) of their mean dimension. This test does not apply to sizes smaller than 6.3mm.The Elongation index of an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than nine-fifths (1.8times) their mean dimension.

Flakiness Index Test. The elongation and flakiness test involves sieving the aggregates through a sieve with long parallel openings (as shown in the diagram below) which measures the amount of aggregates which are elongated which determines the flakiness index. Many specifications state a maximum flakiness index test value of around 35, though

In South Africa, the standard test method used for the determination of flakiness index of coarse aggregates is contained in TMH1 Method B3 (TMH 1 1986). In this method, a metal gauge with rectangular slots representing aggregate sieve sizes are used to obtain the masses of aggregate particles passing the slots. The flakiness index (in percent) is
