Concrete Test Hammers are also known as Swiss Hammers, Schmidt Hammers, or Rebound Hammers. They are versatile tools for assessing the quality of hardened concrete. Although commonly used to estimate in-place compressive strength, concrete test hammers can provide much more value. The complete evaluation of a concrete structure or pavement is ...
Jun 7, 2023 · The rebound hammer test is a non-destructive testing method used to determine the strength of a concrete surface by measuring the rebound of an instrumented hammer from the concrete surface. The rebound hammer test also called the Schmidt hammer test, was invented by Ernst Schmidt in 1948. Procedure of Rebound Hammer Test. The procedure of ...
The Rebound Hammer has been around since the late 1940’s and today is a commonly used method for estimating the compressive strength of in-place concrete. Developed in 1948 by a Swiss engineer named Ernst Schmidt, the device measures the hardness of concrete surfaces using the rebound principle. The device is often referred to as a Swiss Hammer.
