Flakiness Index Sieve | Scitech The accuracy of the slot size is better than 0.1 mm. Aggregate particles are considered as flaky when their thickness is less than 0.6 of their mean sieve size. Aggregate to be classified is separated into seven sieve fractions from 6.3 to 63 mm and each fraction is examined separately. Flakiness Gauge - Construction Materials Testing Equipment 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.

Product Description. BS 812-105.1 Aggregate particles are considered as flaky when their thickness is less than 0.6 of their mean sieve size. Aggregate to be classified is separat
The Flakiness Sieve Series (Bs Standard) dimensions of each sieve comply with the relevant international standard, manufactured from heavy gauge steel sheet and coated with electrostatic paint. The accuracy of the slot size is better than 0.1 mm. TMA-1450 Flakiness Index Sieve Set consists of 7 sieves. For sample preperation 6.3, 10, 14, 20, 28 ... FLAKINESS INDEX - Alberta Ministry of Transportation ... Repeat steps 5 to 7 for the +10 000 F m aggregate using the 14 000 -10 000 Fm slot, and for the + 6 300 Fm aggregate using the 10 000 - 6 300 F m slot. 9. Add the Wt. Retained to the Wt. Passing on each slotted sieve size and record as Total Weight. 10. Calculate the Flakiness Index for each sieve size as follows: Flakiness Index (%) ' Determination of the Flakiness and the Elongation Index for ... COMMENTS Flakiness Index came out to be 52%, which exceeds the limit of 45% so this sample is unsuitable for use although its Flakiness Index is 26%, which is within the limits of 30%. 2.7. Recommendations for Flakiness and elongation The shape tests give only a rough idea of the relative shapes of aggregates. FLAKINESS INDEX (AGGREGATE) - scitech-uk.co.uk
Flakiness Index Test. The flakiness index of aggregates is determined by the percentage of flaky particles contained in it. For base course, and construction of asphalt and cement concrete types the presence of flaky particles is considered undesirable as it may cause inherent weakness with...

Reference Standards IS : 2386 (Part I) – 1963 – Method of test for aggregates for concrete (Part I) Particle size and shape. INDIANA DEPARTMENT OF TRANSPORTATION OFFICE OF MATERIALS ... 1.1 This test method describes a procedure to determine the Flakiness Index (FI) of aggregates. The FI is used as a design input to determine the rate of application of aggregate and asphalt material for seal coats. 1.2 The flakiness index is a measure of the cubical shape of the aggregate which is 1223.1 1223.2 APPARATUS A. conforming to the design and ... pass through the slot. C. Weigh the particles passing the slot to the nearest 0.1 gram. D. Weigh the particles retained on the gauge to the nearest 0.1 gram. 1223.5 CALCULATIONS FOR AN INDIVIDUAL SIEVE SIZE % Flakiness Index = A x 100 A + B Where: A = Weight passing a given slot B = Weight retained on the same slot Report Flakiness Index to the ...
