Journal of the Mechanical Behavior of Materials, 2023 A number of destructive and non-destructive tests were conducted on rock samples collected from various zones in northern Iraq. So far, for Iraqi rocks, few studies have correlated Schmidt hammer rebound (R) with both unconfined compressive strength (UCS)

Repeatability of concrete rebound hardness using comprehensive statistical analysis
Journal of King Saud University: Engineering Sciences, 2023 The reliability of the result significantly affects the use of the Coefficient of Variation (within the test variation), which reflects the variability of the concrete properties rather than the standard deviation.

Calibration and Reliability of the Rebound (Schmidt) Hammer Test [PDF]
Civil Engineering and Architecture, 2013 One of the most widely spread techniques to estimate the compressive strength of concrete is the rebound hammer test, also known as Schmidt Hammer test. In spite of a large number of scientific works trying to calibrate the test, to identify the parameters affecting its results and to estimate its reliability, the original Schmidt curve is still ...
