Vicat Needle Apparatus

About Vicat Needle Apparatus

The Vicat Needle Apparatus is a precision testing instrument used to determine the setting time and consistency of cement paste. It is widely used in construction material testing laboratories to ensure the quality and performance of cement in compliance with standard specifications.

The apparatus consists of a vertical stand, graduated scale, and a movable rod fitted with a replaceable needle or plunger. It is designed to measure the penetration resistance of cement paste at different time intervals, helping determine initial and final setting times accurately.

Manufactured with a sturdy base and corrosion-resistant components, the Vicat Apparatus ensures high accuracy, stability, and long operational life. It is suitable for both laboratory and educational purposes in civil engineering studies.

Key Features:

• High-precision measurement for cement setting time
• Robust and stable base for vibration-free operation
• Corrosion-resistant metallic construction
• Smooth vertical movement of the needle assembly
• Easy to operate and maintain
• Complies with relevant IS / ASTM standards

Applications:

• Cement testing laboratories
• Construction material quality control
• Civil engineering educational institutions
• R&D labs in construction industry

Working Principle:

The apparatus measures the depth of penetration of a standard needle into a cement paste sample over time, indicating the setting characteristics of the cement.
