Overview
What is the Flow Table Calibration?
The Flow Table measures consistency of cement paste, mortar and fresh concrete by dropping through 12.5mm height for 15 drops. Drop height (12.5±0.2mm) is the critical calibration parameter — incorrect height changes energy input and directly affects measured flow diameter.
At Global Lab, flow table calibration per IS 10078 verifies: table diameter (300mm ±1mm), levelness (spirit level), drop height (12.5±0.2mm by calibrated depth gauge), cam mechanism operation and table surface flatness.

Test Procedure
How the Flow Table Calibration is Conducted
-
1
Surface Preparation
A shallow groove (approx. 25mm deep) is cut into the concrete surface using a diamond-tipped cutting tool. The surface is cleaned of dust and debris. -
2
Insert Disc Placement
A specially designed steel insert disc is placed into the groove. A thin rod connects the disc to the pullout apparatus above the surface. -
3
Hydraulic Pullout Force Application
A hydraulic jack applies a steady, controlled pullout force to the insert disc via the reaction ring resting on the concrete surface. -
4
Failure Load Recording
The maximum force at which the concrete cone is extracted is recorded. A digital load indicator provides real-time readings with data logging. -
5
Strength Calculation & Reporting
The pullout force is correlated to cube compressive strength using established calibration curves. NABL-accredited reports are issued via Autovity QLMS.
