Flakiness Index & Elongation Index

The Flakiness Index and Elongation Index are critical measurements used in the evaluation of aggregate materials for construction applications. The Flakiness Index assesses the percentage of aggregate particles that are flat and elongated, impacting concrete workability and strength. A lower Flakiness Index indicates more cubical and compact particles, enhancing concrete quality. Conversely, the Elongation Index measures the percentage of elongated particles, influencing the mix's performance in asphalt and concrete. These indices play a vital role in ensuring that construction materials meet quality standards for durability and structural integrity in various building projects.
