  • Determination of Flakiness and Elongation Index of Coarse

    16/11/2019· Flakiness Index. 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

  • Flakiness Index and Elongation Index of Coarse Aggregates

    The Flakiness Index of aggregates is the percentage by weight of particles whose least dimension (thickness) is less than three- fifths (0.6times) of their mean dimension. This test does not apply to sizes smaller than 6.3mm. The Elongation index of an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than nine-fifths (1.8times) their mean

  • Flakiness Index Test for Aggregates Civil Engineering

    Flakiness Index of aggregate is the percentage by weight of aggregate particles whose least dimension is less than 0.6 of their mean dimensions. This test is applicable to aggregates having size larger than 6.3mm. To calculate the flakiness index of the given sample of aggregates, the weight of each fraction of aggregates passing and retaining on the specified set of sieves is noted first. The

  • Flakiness Index and Elongation Index Test on Coarse

    23/02/2010· Shape tests on coarse aggregates such as flakiness index and elongation Index, its importance in concrete construction, methods of determination is discussed. Shape Tests on Coarse Aggregates: Following tests are conducted on coarse aggregates under shape tests: The elongation index

  • Flakiness Index Test on Aggregates for Shape

    The flakiness index of course aggregate is defined in percentage by weight of aggregate particles and least dimension (thickness) of those particles should not be less than 0.6 times their mean area. Flakiness index test is not applicable for aggregates sizes smaller than 6.3mm. Flaky or elongated course aggregates are disadvantageous to higher workability and stability of mixes. Flakiness

  • Elongation index and flakiness index of coarse aggregate

    Elongation index and flakiness index of coarse aggregate (BS 812 Part:1) Scope: The particle is considered as elongated if its length is more than 1.8 times the mean sieve size of the size fraction to which the particle belongs. Similarly, the particle is considered as flaky if its thickness is less than 0.6 times the mean sieve size of the size fraction. Elongated and flaky particles have a

  • Flakiness and Elongation Index of Aggregate Gilson Co.

    Determinations for the flakiness index and flakiness and elongation of aggregate use a British Standard classification system consisting of a Thickness Gauge for determining flakiness index and a metal Length Gauge for determining elongation index. Aggregate is separated into seven sieve fractions from 63—6.3mm and each fraction are evaluated separately. Test aggregates must be sieved using
