Description

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

Complete AZA0975 kit includes:

  • Precision-machined conical funnel

  • Heavy-duty metal stand

  • Cylindrical measuring container

  • Base plate for stable setup

  • User manual
