Flakiness

Well shaped aggregates have following advantages:-

Flakiness index as per amendment 26.6 % The flakiness index calculated by the amendment is higher than that by old method. The amendment seems to give logical and more accurate representation of flakiness however it specifies that a minimum of 200 pieces should be retained on each sieve fraction for ...

Flakiness Gauge for

Introduction This method is based on the classification of aggregate particles as flaky when they have a thickness (smallest dimension) of less than 0.6 of their nominal size, this size being taken as the mean of the limiting sieve apertures used for determining the size fraction in which the ...

A revisit to aggregate shape parameters

Various shape parameters As per Indian standard IS-2386(I) (1999) flakiness and elongation index and angularity number are used as a measure of aggregate shape.

Testing aggregates

When the flakiness index has been determined for individual size-fractions (see note to 7.5), the overall flakiness index of the aggregate is calculated by summing the appropriate masses (M ², M ³ etc.) or as the weighted average of the individual sire-fractions. 9 Precision Estimates of the repeatability ...
