Rebound Hammer test is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. The rebound hammer is also called as Schmidt hammer that consist of a spring controlled mass that slides on a plunger within a tubular housing.

How does it work? ASTM C805, “Standard Test Method for Rebound Number of Hardened Concrete”, summarizes the procedure as “A steel hammer impacts, with a predetermined amount of energy, a steel plunger in contact with a surface of concrete, and the distance that the hammer rebounds is measured.”
Learn how to use a concrete test hammer to assess the quality and strength of hardened concrete. Find out the types, selection, preparation, and correlation of rebound numbers with compressive strength.
Jul 9, 2019 · The rebound hammer is a nondestructive testing apparatus, whereby the rebound of the spring driven mass is measured after its impact with concrete surface. The output of the rebound hammer is referred to as rebound number and are correlated with surface hardness of concrete.
Sep 14, 2023 · Learn how to use the Rebound Hammer Test, a non-destructive method to measure the hardness and compressive strength of concrete. Find out the basic principles, equipment, calculations, and applications of this technique.
Jun 21, 2024 · The rebound test, sometimes called the Schmidt Hammer test, is a non-destructive testing for measuring concrete’s strength and surface hardness. It works by determining the rebound velocity of concrete test hammers. This innovative technique allows engineers to: Evaluate the suitability of hardened concrete for its intended use.
The rebound hammer method could be used for: assessing the likely compressive strength of concrete with the help of suitable corelations between rebound index and compressive strength, assessing the uniformity of concrete, assessing the quality of the concrete in relation to standard requirements, and.
