Concrete Rebound Hammer

Concrete Rebound Hammer – Reliable Non-Destructive Testing of Concrete Strength

A Concrete Rebound Hammer, also known as a Schmidt Hammer, is one of the most widely used non-destructive testing (NDT) instruments for assessing the compressive strength and uniformity of hardened concrete. By measuring the rebound of a spring-driven mass impacting the concrete surface, this simple yet highly effective tool provides quick, repeatable, and cost-efficient results directly on-site.

Qualitest offers a full range of digital and analog concrete rebound hammers, ensuring that contractors, engineers, and testing laboratories can select the right model for their specific needs.

Applications of Concrete Rebound Hammers

Concrete rebound hammers are used across a wide spectrum of industries and applications, including:

• On-site concrete strength testing for buildings, bridges, tunnels, and highways
• Quality control in construction projects to verify compressive strength uniformity
• Maintenance and inspection of existing structures, ensuring continued safety and compliance
• Comparative testing of concrete batches to identify variations in curing or workmanship
• Preliminary structural assessments before more advanced testing methods (core drilling, ultrasonic, etc.)

This versatility makes the rebound hammer an indispensable tool for structural engineers, quality inspectors, and field technicians.

Standards and Compliance

Concrete rebound hammers are designed to comply with international standards, ensuring reliable and comparable results worldwide. Commonly referenced standards include:

• ASTM C805 / C805M – Standard Test Method for Rebound Number of Hardened Concrete
• EN 12504-2 – Testing concrete in structures, Part 2: Non-destructive testing – Determination of rebound number
• BS 1881: Part 202 – Recommendations for surface hardness testing by rebound hammer
• ISO 1920-7 – Testing of concrete, Part 7: Non-destructive tests – Rebound hammer
• JIS A1155 – Japanese Industrial Standard for testing concrete by rebound hammer

Adherence to these standards guarantees that test results are consistent, traceable, and suitable for both quality control and compliance documentation.

The Role of the Anvil

A crucial component in any concrete rebound hammer is the reference anvil. The anvil is used to verify the calibration and accuracy of the hammer. By providing a standard reference surface with a known rebound value, the anvil ensures that test results remain accurate and within tolerance. Regular use of the anvil for calibration checks is essential for maintaining confidence in test data, especially for critical projects where structural safety is paramount.
