Description

This standard specifies a method for determining the flakiness index of coarse aggregate that passes a sieve of aperture size 75 mm and that is retained on a sieve of aperture size 4 750 μm.
NOTE The flakiness index is a measure of the flatness of an aggregate, which has an effect on most of its uses in the construction industry. The flakiness index is the mass of particles in the aggregate (expressed as a percentage of the total mass of the aggregate test sample) that will pass slots of specified width for the appropriate size fraction of the aggregate.
