The Determination of Particle Shape is one of the most important aggregate tests in civil engineering and construction quality control. The shape of coarse aggregates has a direct influence on the strength, workability, durability, and long-term performance of concrete, asphalt, and pavement structures. Irregularly shaped aggregates, such as flaky or elongated particles, can reduce the structural integrity of construction materials and negatively affect compaction and load-bearing capacity.
QC LAB SOLUTION is a trusted supplier of Aggregate Testing Equipment in Bangladesh, offering reliable solutions for determining particle shape using internationally recognized testing standards. Our equipment is widely used by quality control laboratories, construction companies, consultants, universities, research institutions, and government organizations.
The Determination of Particle Shape is a laboratory test used to evaluate the proportion of flaky and elongated particles within a coarse aggregate sample. Since aggregate shape significantly affects the performance of concrete and asphalt mixtures, this test helps engineers ensure that only high-quality aggregates are used in construction projects.
The test generally includes:
These tests are commonly performed according to international standards such as BS 812, EN 933, and other applicable specifications.
Aggregate shape plays a vital role in the mechanical performance of construction materials. Well-shaped aggregates improve interlocking, reduce voids, enhance compaction, and increase the strength of concrete and pavement layers.
Poorly shaped aggregates may lead to:
By determining the particle shape before construction, engineers can select aggregates that meet project specifications and deliver long-lasting performance.
The Flakiness Index Test measures the percentage of particles whose thickness is less than a specified proportion of their nominal size. Flaky particles are thin and flat, making them less desirable for structural applications because they tend to break under load and reduce aggregate interlock.
The Elongation Index Test determines the percentage of aggregate particles whose length exceeds the specified limit relative to their size.
Elongated particles may create weak points within concrete and asphalt mixtures, affecting compaction and structural performance.
