FLAKINESS SIEVE SET AZA0973

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.
