INDEX APPARATUS (FLOW COEFFICIENT OF FINE AGGREGATES) AZA0975

Description

Importance of Flow Coefficient Test

The flow coefficient indicates how easily fine aggregates flow under gravity through a standardized funnel:

• Lower values generally indicate better-rounded, more workable sand

• Higher values suggest angular, flaky, or poorly graded particles

This directly affects water demand, cement consumption, workability, and final strength of concrete.

Q2: Does this comply with IS standards?
Yes, it is fully compliant with IS 2386 (Part I).

Q3: Can it be used for all types of fine aggregates?
Yes, it can be used for natural sand, crushed sand, and manufactured sand.

Q4: Is assembly required?
The apparatus is supplied in easy-to-assemble parts with full instructions.

Q5: How often should it be checked for accuracy?
A periodic check every 6 months is recommended for high-precision laboratories.
