WebNov 16, 2024 · The flakiness index of aggregates is the percentages by weight of particles whose least dimension (thickness) is less than 3/5 th (0.6) of their mean dimension. The test does not apply to sizes smaller than 6.3 mm. [For example, the mean sieve size for an aggregate piece passing through 50 mm and retained on 40 mm sieve is (50+40)/2 i.e. … WebDescription. Used to determine if aggregate particles are to be considered flaky, i.e. their thickness is less than 0.6 of their nominal size. Each sieve is made from heavy gauge steel. To evaluete the thickness and the elongation index of the aggregates particles, thickness gauge code 47-D0540 and length gauge code 47-D0541 can be used.

WebOct 23, 2024 · The elongation index of an aggregate is the percentage by weight of particles in it whose greatest dimension is more than 1.80 times their mean dimension. It is measured by a length gauge. A combined value of flakiness and elongation index is to be determined for a sample of aggregates. The sequence of tests are conducted is the … WebFLAKINESS INDEX AND ELONGATION INDEX TEST. INTRODUCTION : This method describes the procedure for the determination of the Flakiness Index of aggregrate that has not more than 5% retained on a 26.5 mm AS Test Sieve and no more than 5% passing a 4.75 mm AS Test Sieve .
