Nunes Instruments Vee Bee Consistometer

The Vee-Bee Consistometer is a precision instrument used to measure the workability of concrete. Workability is expressed in Vee-Bee degrees, representing the time it takes for concrete to flow and make contact with an acrylic disc during vibration. It is particularly useful for concrete with low slump where conventional slump tests are difficult to perform.

The equipment includes a vibrating table supported on elastic mounts to ensure controlled vibration, and a tamping rod for proper compaction of the concrete sample. Constructed from sheet metal or steel, the instrument is durable, corrosion-resistant, and suitable for laboratory or on-site testing. It is electrically powered and designed to comply with IS:1199 and IS 10510 standards.

Key Features

• Measures concrete workability in Vee-Bee degrees for accurate evaluation.
• Can also determine slump value for versatile testing.
• Sturdy vibrating table with start/stop switch and elastic supports.
• Supplied with a 16 mm × 600 mm tamping rod for sample preparation.
• Made from durable sheet metal or steel for long-term use.
• Electrically powered, compatible with 220V AC or 415V, 3-phase, 50Hz supply.
• Lightweight and portable, weighing 10–25 kg depending on model.
• Complies with IS:1199 and IS 10510 standards for testing.

Applications

• Measurement of concrete workability in laboratories and construction sites.
• Evaluation of low-slump or stiff concrete where traditional slump tests are impractical.
• Quality control in concrete production and civil engineering projects.
• Used in research and educational laboratories for concrete mix analysis.
