May 16, 2014· The Schmidt hammer is being widely used for estimating the uniaxial compressive strength (UCS) of rocks because of its simplicity, rapidity and portability. However, determination of the Schmidt hardness (R) in laboratory conditions is sometimes very difficult for weak rocks due to the fact that samples can be broken during the test, as well as sample scarcity.

Aug 05, 2018· Concrete Rebound hammer test was first covered by IS 13311 (Part 2) – 1992. Swiss engineer Ernst Schmidt is the name of the scientist who first introduced Rebound hammer test, and it is also called as Schmidt hammer test or Swiss Hammer Test. Now let's dive into rebound hammer test:
Proceq's high-tech and intuitive NDT products solve material inspection challenges for a broad range of applications in demanding environments.
Concrete cores can be taken from hardened concrete for testing, but Non-destructive Test (NDT) equipment enables the testing of in-situ concrete or concrete samples. ELE provides crack detection microscopes, and a (Schmidt) rebound hammer, or test hammer, for measuring surface hardness and penetration resistance.
Jul 03, 2017· The device used in the test known as Schmidt hammer or rebound hammer, uses a spring and measures the hardness of concrete surface using the rebound principle [2]. The rebound hammer test is codified in ASTM C805 [3] and CSN EN 12504-2 [4]. Acceptability of rebound hammer test is evaluated by different research works and studies.
