Testing of concrete by rebound method: Leeb versus Schmidt hammers
Materials and Structures, 2018Hardness is considered as an important property of concrete; it can be used to estimate compressive strength of concrete in situ. The classic Schmidt rebound hammer is the most popular nondestructive method to measure concrete surface hardness, while the Leeb rebound hammer has been extensively studied in geological and metallographic fields over ...

Advancing the Rebound Hammer Method: A New Concrete Test Hammer
2011The concrete test hammer patented by Proceq’s Ernst O. Schmidt at the beginning of the 1950’s is without a doubt the most widely used NDT instrument worldwide for rapid assessment of the condition of a concrete structure. Despite this fact, the validity of the method remains a hotly debated topic amongst experts in the NDT field. This is largely due to

Evaluation of rubbercrete based on ultrasonic pulse velocity and rebound hammer tests
Construction and Building Materials, 2011Abstract Several research works have been carried out to study the fresh and hardened properties of concrete containing crumb rubber (rubbercrete) as a replacement of fine aggregate. The outcomes of these studies have highlighted the advantages and disadvantages of rubbercrete compared with conventional concrete mixtures.

Strength Evaluation of In-Situ Concrete by Rebound Hammer and Core Testing
Cement, Concrete, and Aggregates, 1994Abstract This paper describes the results of an extensive field investigation where the quality of in-place concrete flatwork was evaluated. Nondestructive testing (NDT) was carried out using ultrasonic pulse velocity and rebound hammer techniques to establish a correlation with compressive strengths of core tests.

A Comparative Analysis of the Rebound Hammer and Ultrasonic Pulse Velocity in Testing Concrete
2012This 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.
