WebApr 8, 2024 · The flakiness index is the total weight of material passing through the gauge to the total weight of the sample. It is expressed in terms of percentage. Weigh the flaky material passing the gauge to an accuracy of at least 0.1 per cent of the test sample. The formula for flakiness index is. F.I = (Weight of aggregate passing through the slot of ... WebFlakiness Index: - The flakiness index is the percentage by weight of particles whose least dimension (thickness) is less than three-fifths (0.6) of their mean dimension. Elongation Index: - The elongation index is the percentage by weight of particles whose greatest dimension (length) is greater than one fifth times (1.8) their mean dimension.
