Overview
What is the Vicat Apparatus Calibration?
The Vicat Apparatus measures cement consistency (10mm plunger) and setting time (1mm needle) per IS 4031 Parts 4 and 5. IS 5513 specifies plunger diameter, needle diameter, moving rod mass (300±1g), scale graduation and reference zero. Out-of-specification components produce incorrect results.
At Global Lab, Vicat calibration per IS 5513 verifies: plunger diameter (10±0.05mm), Vicat needle diameter (1.13±0.05mm), moving rod + plunger mass (300±1g), scale reading vs actual penetration, and guide frame alignment.
Non-Destructive
Minimal surface preparation. Structure integrity is preserved throughout testing.
Fast Turnaround
On-site results within hours. Digital reports dispatched within 24 hours.
NABL Certified
All test and calibration results are backed by traceable measurements and standardized procedures.
Pan-India Coverage
Site engineers deployed across 7 lab locations and all major project sites.
Digital Reporting
Access reports anytime via Autovity QLMS client dashboard — zero paperwork.
High Accuracy
Results correlated to cube compressive strength with ±2% precision range.

Test Procedure
How the Vicat Apparatus 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.
