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 ...

Comparatively Study of Non-Destructive test with different methods in various curing days [PDF]

E3S Web of Conferences
In non-destructive testing, materials, components, or assemblies are inspected, tested, or evaluated without being destroyed. In nondestructive testing, materials, components, and assemblies are evaluated for quality and integrity without damaging them ...

A Comparative Analysis of the Rebound Hammer and Ultrasonic Pulse Velocity in Testing Concrete

Nigerian Journal of Technology, 2012
This work presents a study on the comparison between some non-destructive testing tech-niques (Rebound Hammer and Ultrasonic Pulse Velocity). Tests were performed to com-pare the accuracy between the rebound hammer and the ultrasonic pulse velocity methodin estimating the strength of concrete.

Estimation of uniaxial compressive and indirect tensile strengths of intact rock from Schmidt hammer rebound number

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)
