Answer / sjtbehera

Flaky is the term applied to aggregate or chipping that are
flat and thin with respect to their width and length.
Aggregate particlie are said to be flakey when there th. is
less then .06 of their mean size.

Aggregates which are flaky and/or elongated will often
lowerthe workability of a concrete mix and may also affect
longterm durability. In bituminous mixtures flaky
aggregatemakes for a harsh mix and may also crack and break
up during compaction and rolling index.

Answer / richard asmah

flakiness means flat
and elongation means long and thin

Answer / sowmiya b.e

Elongation index is the % by weight of particles whose greater dimension is greater than 4/5 of the mean dimension

ELONGATION INDEX = (wt of aggregate retained on specified gauge) / (total wt of aggregate taken)


Flakiness index is the % by weight of particles whose least dimension is lesser than 3/5 of the mean dimension

FLAKINESS INDEX = (wt of aggregate passing thro thickness gauge) / ( total wt of aggregate taken)

Answer / ashish

Flakiness index is the % weight of particle whose size is 0.6 times greater than the mean particle size ...
Moreover flakiness means where a particle or body whose 2 dimensions are bigger as compared to 3rd..
And elongation index is the % weight of thise particle whose avg size of particle is 1.8 times the mean size in sample taken..and in this 1 dimension is larger as compared to others2..
