ELONGATION AND FLAKINESS TEST

OBJECTIVE: 

Flakiness index

To determine the flakiness index of aggregate. The flakiness index of aggregates is the percentage by weight of particles in them whose  dimension (thickness) is less then three-fifths of their mean dimension

Elongation Index

To determination the elongation index of aggregate. The elongation index   of  aggregates is the percentage by weight of particles in them  whose greatest dimension ( length )  is greater than 1 4/5 time their mean dimension.
