WebMar 11, 2024 · Flakiness Index and Elongation Index are two important measurements for evaluating the quality of aggregates. The Flakiness Index is a measure of the particle size distribution of the material, focusing on the flatness of the material’s particles. Together, these measures are used to determine the suitability of the material for its intended use.
