Evaluate aggregate Quality using BS 812 Part 105 to reduce flaky particles and improve strength, durability, and performance of concrete and asphalt.
The quality of aggregates plays a critical role in the strength and durability of concrete and asphalt. One of the key factors affecting aggregate performance is particle shape, particularly the presence of flaky particles.
Flaky particles are defined as aggregates whose thickness is less than 0.6 times their nominal size. These particles tend to break easily under load, resulting in reduced strength, poor compaction, and lower durability of the final structure.
The Flakiness Index test, conducted in accordance with BS 812: Part 105, is used to determine the percentage of such weak and undesirable particles in a given aggregate sample. The test involves sieving aggregates into different size fractions and passing them through a thickness gauge to identify flaky particles.
A higher flakiness index indicates a greater proportion of weak particles, which can negatively impact the performance of concrete and asphalt mixes. By controlling and minimizing the flakiness index, engineers can ensure better interlocking of aggregates, improved load distribution, and enhanced structural integrity.
At our accredited laboratory, the Flakiness Index test is performed under strict quality standards to deliver accurate and reliable results. This test is essential for quality control in construction projects, ensuring compliance with specifications and improving overall material performance.
Incorporating flakiness index testing in your material evaluation process helps minimize weak particles, optimize mix design, and achieve long-lasting, high-quality construction.
