INDEX APPARATUS (FLOW COEFFICIENT OF FINE AGGREGATES) AZA0975
The AZA0975 Flow Coefficient Index Apparatus is a precision laboratory instrument designed to measure the flow coefficient of fine aggregates, such as natural sand and crushed sand. This test helps evaluate workability, particle shape, and grading, which are critical factors in concrete and mortar mix performance. The apparatus is manufactured in compliance with IS 2386 (Part I) and is widely used in civil engineering laboratories and construction quality control departments.
Key Features
-
Measures flow coefficient of fine aggregates
-
Fully compliant with IS 2386 (Part I)
-
Evaluates workability and particle shape characteristics
-
Supplied as a complete set: funnel, stand, cylinder, and base plate
-
Precision-machined components for consistent results
-
Corrosion-resistant, durable construction
-
Easy manual operation for laboratory and field use
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
