Concrete hardness testing (strength estimation)

Concrete hardness and strength test are performed using non destructive method such as Schmidz hammer or laboratory based destructive test. 

The Schmidt rebound hammer is a surface hardness tester. The Schmidt hammer works on the principle of rebound due to elastic effect. 

Our expert engineers and technicians use this rapid and cost-effective technique to evaluate the integrity of concrete elements non-destructively.

Applications:

  • Assessing concrete quality in existing structures

  • Evaluating strength variations in different sections

  • Ensuring structural safety in buildings, bridges, and tunnels

  • Supporting renovation and restoration projects

Operation and interpretation of this technique requires expertise, as it does have limitations particuarly depending on the surface condition and age of the concrete. More accurate and conclusive methods such as compressive strength testing on extracted concrete cores are available. Contact LMATS for more information.
