Rebound Hammer (Schmidt Hammer) Testing Services
On-site Rebound Hammer Testing for rapid assessment of concrete surface hardness, compressive strength uniformity, and structural condition. Testing is performed by appropriately qualified and certified NDT personnel in accordance with applicable codes, standards, specifications, and approved procedures.
Principle & Testing Methodology
The Rebound Hammer (Schmidt Hammer) measures the rebound value of an elastic mass impacting a plunger held against the concrete surface. The rebound distance depends on the surface hardness of the concrete, which correlates directly with compressive strength when calibrated against core test data.
Defects & Discontinuities Detected
- Localized weak patches and improper concrete curing
- Surface carbonation and concrete skin degradation
- Strength uniformity variations across multiple columns, beams, and slabs
- Poor concrete compaction at formwork faces
Typical Industrial Applications & Components
- Rapid survey of large industrial concrete floor slabs and columns
- Comparative quality control across repetitive precast elements
- Assessment of concrete maturity before removing shuttering/formwork
- Structural condition surveys for building expansion permits
Applicable Materials
Cast-in-place concrete structures, precast structural units, and masonry brickwork.
Technical Specifications
IS 13311 (Part 2), ASTM C805, BS 1881: Part 202, EN 12504-2
