DLC VIBRATING HAMMER FOR CONCRETE MOULDS 

DLC Vibrating Hammer for Concrete Moulds

Product Code: MSI 2048

The DLC Vibrating Hammer is an advanced electrical compaction tool engineered for the rapid consolidation of fresh concrete samples inside testing molds. Designed in accordance with international testing frameworks including ASTM C 232 and EN 480-4, this professional-grade apparatus provides a much faster, cleaner, and more efficient method of consolidation compared to traditional manual impact hammering.

In addition to standard sample casting preparation, this specialized tool is key for evaluating the relative quantity of mixing water that will bleed from a sample of freshly mixed concrete. The compact, handheld unit features an efficient power-to-weight ratio, weighing approximately 6 kg, and is supplied ready-to-run with a heavy-duty tamping foot and an industrial attachment shank.

🎯 Applications

• Fast Compaction of Concrete Cubes, Cylinders, and Beam Samples

• Determination of Concrete Bleeding Water Quantity (ASTM C232)

• High-Frequency Testing Schedules in Commercial Labs

• Ready Mix Concrete (RMC) Quality Audits and Mix Verification

• Civil Engineering & Concrete Material Calibration Laboratories

• On-Site Infrastructure Construction Field Testing

⭐ Features

• Multi-Standard Compliance: Fully satisfies the rigorous compaction and bleeding test protocols of ASTM C 232 and EN 480-4.

• Rapid Mechanical Vibrations: Delivers localized vertical high-frequency energy that finishes compaction significantly faster than manual impact tamping.

• Dual Testing Application: Serves as a direct compaction tool for standard strength specimens and as the driving energy source for concrete bleed water analysis.

• Ergonomic, Compact Housing: Streamlined outer dimensions measuring 290 x 255 x 350 mm make it highly manageable for handheld operation.

• Complete System Supply: Furnished complete with one precision-flat circular tamping foot and a robust attachment connecting shank.

🔬 Working Principle

Freshly mixed concrete is poured into a sample mold or a standardized bleeding container in designated layers. The operator locks the connecting shank and tamping foot onto the vibrating hammer head, plugs the unit into an electrical outlet, and lowers the foot onto the concrete surface.

When activated, the internal motorized eccentric weights deliver rapid mechanical oscillations downward through the tamping foot. This energy fluidizes the dry mortar paste, driving coarse aggregates closer together to seal out trapped air pockets while allowing excess bleed water to float up uniformly for volume measurement per ASTM C232 rules.

💡 Advantages

• Reduces worker arm strain by substituting demanding manual sledge/tamping work with rapid electric motor power.

• Guarantees uniform compaction density, eliminating human error variations across sample sets.

• Ultra-compact, lightweight frame (6 kg) allows for effortless transport in the boot of a vehicle for on-site field testing.

• Dual-purpose utility saves laboratory counter space and capital expenditure by covering both compaction and bleed testing.
