This test is used to determine the particle shape of the aggregate and each particle shape being preferred under specific conditions. Rounded aggregates are preferred in concrete roads rigid pavements as the workability of concrete increases due to the less friction between the surfaces. Angular shape of the particles is desirable in granular base coarse flexible pavement due to better interlocking and increased stability.

Particle shape and surface texture influence the properties of freshly mixed concrete more than the properties of hardened concrete. Rough-textured, angular, and elongated particles require more water to produce workable concrete than smooth, rounded compact aggregate. Consequently, the cement content must also be increased to maintain the water-cement ratio. Sieves required are 63, 50, 40, Length Gauge have length equal to 1.

Flakiness Index and Elongation Index Test on Coarse Aggregates

Type of pavement. Bituminous carpet. Bituminous Penetration macadam. Bituminous surface dressing single coat, double coats and precoated.

Built up spray grout. Bituminous macadam. Thanks for reading this article. What is the Flakiness and Elongation Index of Aggregate? The flakiness index of aggregate is defined as the percentage by mass of particles stones in it whose least dimension thickness is less than three-fifths of their average dimension. The elongation index of aggregate is defined as the percentage by mass of particles stones in it whose greatest dimension thickness is greater than one and four-fifths of their average dimension.

Thus, evaluation of shape of the aggregate particles, particularly with reference to flakiness and elongation is necessary. Here I have explained about the flakiness and elongation index test of coarse aggregate. Read definition, apparatus, IS code, procedure, observations, formula, result, lab report about flakiness and elongation index test of coarse aggregate. Save in pdf. Calculations and Observations Table 1: Dimensions of Thickness gauge.

Table 2: Dimensions of Length gauge. Surface texture and aggregate shape influence the properties of freshly mixed concrete more than the properties of hardened concrete. Rough-textured, angular and elongated aggregates require more water to produce workable concrete than smooth, rounded compact aggregates. The aggregate shape tests give only a rough idea of the relative shapes of aggregates.

Flaky aggregate particles and elongated aggregate particles should be avoided in pavement construction, particularly in surface course. Workability of cement concrete is reduced. IRC recommendations for maximum limits of flakiness index are as given below. Read also -. Significance of flakiness index and elongation index test of aggregate.

Flaky and elongation particles are considered undesirable as they cause weakness of the pavement.
