Qualitest supplies the high-strength concrete test hammer series to assist structural evaluation teams in checking dynamic surface hardness across concrete mixes rated from 20 MPa to 110 MPa. Built with impact outputs from 4.5 J up to 9.8 J, these portable mechanical units yield consistent rebound values on dense commercial pours without destroying local material. US general contractors, testing agencies, and field technicians choose these tools to audit high-rise columns and roadway structures quickly.

Overview of the Concrete Test Hammer

On heavy-duty commercial construction projects across the United States, inspecting high-performance concrete demands strike force well beyond what ordinary rebound devices provide. Qualitest offers the high-strength concrete test hammer line, featuring the QualiCRH-1000A, QualiCRH-550A, and QualiCRH-450A, to meet these demanding assessment requirements.

Every instrument works via a spring-driven mass striking against an impact plunger placed firmly against the surface, bouncing along an internal graduated scale to display a rebound index without fracturing fine aggregates or overwhelming the gauge.

This non-destructive evaluation technique delivers immediate readings on dynamic surface hardness across newly cured or aged slabs before crews ever commit to core drilling. American field inspectors can screen extensive structural sections swiftly, and your team can pair the instrument alongside ultrasonic pulse velocity devices using the SonReb approach to evaluate surface rebound and internal mass density together.

Key Features

Each rebound test hammer in our line delivers specific operational advantages for American field crews:

  • Elevated Impact Force Mechanics: Conventional testing units only produce 2.207 J, which often falls short against modern high-performance mixtures. By offering 4.5 J, 5.5 J, and 9.8 J impact energy levels, these units supply adequate punch to test dense C50 through C110+ placements without crushing surface grains.
  • QualiCRH-1000A for Massive Structural Members: Delivering a 9.8 J impact with a 140 ± 0.5 mm stroke length and a 1000 ± 45 N/m tension spring stiffness, this 3.5 kg model provides deep kinetic penetration on massive commercial structural elements ranging from 50 to 80 MPa.
  • QualiCRH-550A for Compact Handling: Weighing just 1.28 kg with outer dimensions of Ø54 × 350 mm, this portable unit combines 5.5 J energy, an 18 ± 1.0 mm rebound pole radius, and an 1100 ± 50 N/m spring stiffness to assist technicians working in congested rebar cages or tight utility spaces on 60 to 90 MPa pours.
  • QualiCRH-450A for Broad Strength Coverage: With a 4.5 J (1 kgf·m) impact, a 100 ± 0.5 mm travel distance, and a 900 ± 40 N/m spring rating, this 3 kg unit spans 20 to 110 MPa, making it a flexible choice for general contractors handling C50 to C100 concrete.
  • Verified Steel Anvil Calibration: Consistency remains simple to verify on site using a dedicated steel anvil, confirming average rebound baseline values of 83 ± 2 for the 1000A and 550A instruments, and 88 ± 2 for the 450A instrument.

Product Applications & Operating Environments

This equipment supports quality assurance across large-scale civil works and private commercial developments throughout the country:

  • High-Rise Developments: Verification of high-load foundation slabs, vertical columns, and structural shear walls built using C50 to C110+ concrete formulations.
  • Highway and Bridge Infrastructure: Surface hardness checks across bridge piers, concrete abutments, elevated highway spans, and pre-stressed support beams where non-destructive confirmation protects critical structures.
  • Thick and Massive Concrete Placements: Use of the QualiCRH-1000A on deep structural foundations requiring substantial kinetic impact to record representative internal values.
  • Tight Jobsite Locations: Deployment of the lightweight QualiCRH-550A within tight formwork, narrow utility chases, or congested structural joints.
  • Standard Grid Testing Protocols: Field implementation involving 10 to 16 impact readings spaced a minimum of 25 mm apart at a direct 90-degree angle, allowing technicians to filter out anomalies and calculate dependable average strength estimates.

When budgeting for your next project, our team can help you review equipment choices and look over concrete rebound hammer price points that align with your firm's technical requirements.
