LASER-BASED APPROACH FOR DETERMINING FLAKINESS INDEX OF ... slot gauge allow for considerable variation in the shape of different aggregates passing through. This may result in poor repeatability of flakiness index obtained from the same material. Similarly, two different aggregates having the same flakiness index may in reality differ significantly in terms of their shape and volume. A revisit to aggregate shape parameters - IITK • The conventional shape parameters like, flakiness index and elongation index are characteriz ed with reference to the slot size s. This size is neither the length, or, width or, height of the aggregates measured by the DIP technique, which uses a ‘box principle’ to circumscribe the aggregates (Maerz 2004). It is, therefore, difficult to China Flakiness Index Sieve/ Grid Sieve for Flakiness Index ...

For determining flakiness index. Particle is flaky when its thickness (smallest dimension) is less than 0.6 of the mid-size of the sieve fraction. Gauge has seven, labeled slots for manual evaluation of particles in the seven openings. The mass of all flaky particles (passing appropriate slots) as percent of the sample is the flakiness index. ATT-49/95 FLAKINESS INDEX 1.0 SCOPE 2.0 EQUIPMENT 10. Calculate the Flakiness Index for each sieve size as follows: 11. Total the weights in the "Weight Passing" and "Total Weight" columns, entering the figures in the "Sum of Weights" line. 12. Calculate the Total Flakiness Index in percent as follows: 3.1 Median Aggregate Particle Size at 50% Passing 1. Flakiness Index Sieve Sets Bs by Parsros Material Testing ... The accuracy of the slot size is better than 0.1 mm. PRS-A300 Flakiness Index Sieve Set consists of 7 sieves. For sample preperation 6.3, 10, 14, 20, 28, 37.5, 50 and 63 mm aperture sizes test sieves should be ordered seperately.

Flakiness sieve test set 47-D0415 General description Used to determine if aggregate particles are to be considered flaky, i.e. their thickness is less than 0.6 of their nominal size.
The accuracy of the slot size is better than 0.1 mm. UTA-0410 Flakiness Index Sieve Set consists of 7 sieves. For sample preperation 6.3, 10, 14, 20, 28, 37.5, 50 and 63 mm aperture sizes test sieves should be ordered seperately. SD 203 Method of Test for Flakiness Index plate. The size of the slots required for each fraction is given in table 1 below. NOTE: If the material retained on any one of the sieves comprises less than 4% of the total weight of the sample, that material shall be omitted from the flakiness index test. If a 5/8” Flakiness and Elongation - pcte.com.au The accuracy of the slot size is better than 0.1 mm. UTA-0410 Flakiness Index Sieve Set consists of 7 sieves. For sample preparation 6.3, 10, 14, 20, 28, 37.5, 50 and 63 mm aperture sizes test sieves should be ordered separately. TMH1 - Method B3T - CSIR
