Description
Why Flakiness Index Testing Matters
Flaky particles are defined as particles whose thickness is less than 0.6 × their mean sieve size. A high flakiness index can negatively affect:
-
Mechanical interlock in concrete
-
Load-bearing capacity in pavements
-
Compaction efficiency
-
Long-term durability of structures
The AZA0973 helps identify and control flaky particles before aggregates are used in critical construction applications.

FAQ
Q1: What is the flakiness index?
It is the percentage by weight of particles whose thickness is less than 0.6 × the mean particle size.
Q2: Why is flakiness harmful in construction?
Flaky particles reduce strength, compaction quality, and durability of concrete and bituminous layers.
Q3: Is AZA0973 IS standard compliant?
Yes, it is fully compliant with IS 2386 (Part I).
Q4: Can it test different aggregate sizes?
Yes, the set includes gauges for sizes from 6.3 mm to 63 mm.
Q5: How is the test performed?
Aggregates are passed through the appropriate slot gauge. Particles that pass through are classified as flaky and weighed to calculate the flakiness index.
