Concrete Cube Vibration Machine

Concrete Cube Vibration Machine – Uniform Compaction of Concrete Cubes

The Concrete Cube Vibration Machine is a table vibrator specifically designed for uniform compaction of fresh concrete inside cube and cylinder moulds during specimen preparation. It eliminates manual rodding variability and ensures consistent, void-free specimens as required by IS 516 Part 6 and ASTM C192.

Why Use a Vibration Machine?

Manual rodding (tamping) can leave air voids in concrete specimens, leading to underestimated compressive strength values. Mechanical vibration consolidates the concrete uniformly, expels entrapped air, and produces specimens that more accurately represent in-situ concrete strength.

Technical Specifications

• Vibration frequency: 50 Hz (3,000 vibrations/min)
• Amplitude: Adjustable, typically 0.3–0.5 mm
• Table size: 300 × 300 mm or 400 × 400 mm (model dependent)
• Motor: 0.5 HP single-phase, 230V/50Hz
• Mould capacity: 1–4 cubes (150 mm) or 1–2 cylinders simultaneously
• Frame: Mild steel, powder-coated, floor-mounted with anti-vibration feet
• Vibration timer: Adjustable 0–60 seconds

Applications

• Compaction of 150 mm, 100 mm concrete cubes and 150×300 mm cylinders
• Compaction of beam moulds for flexural strength testing
• Cement mortar cube compaction (with appropriate mould adapter)

Standards

IS 516 Part 6 (2020), ASTM C192, BS 1881 Part 108.
