Does the flakiness of aggregate affect the strength of
More flaky the aggregate, the density decreases. Means compaction of aggregates is less and voids are more. So more fines are required to take up this voids. Flaky aggregates have more area. In both cases more cementation

The procedure of the impact value test includes the following series of steps: 1. The aggregate samples of size 10mm to 12.5mm (passing through 12.5mm sieve and retained on 10mm sieve) are first taken and oven-dried at a temperature ranging from 100 degrees Celsius to 110 degrees Celsius for about four hours. 2.

2021| Flakiness Index Test Engineering Civil World
The Flakiness Index of aggregate is the percentage by weight of particles in it whose least dimension (thickness) is less than three-fifths of their mean dimension. That means the test is not applicable to sizes smaller than 6.3 mm aggregate. The flakinesselongation index test is connected as thickness gauge and length gauge respectively.

Flakiness and Elongation Index of Aggregate
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. Generally, flat and elongated particles are avoided or are limited to about 15 % by weight of the total aggregate.
