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.
Components Supplied

-
Precision-machined conical funnel
-
Heavy-duty metal stand
-
Cylindrical measuring container
-
Base plate for stable setup
