Rebound Hammer Test: An Investigation into Its Reliability in Applications on Concrete Structures
Advances in Materials Science and Engineering, 2020 The issue of concrete strength often arises in civil engineering practice, either due to quality control of new constructions or due to the assessment of existing structures. To this aim, one of the most widely spread techniques is the rebound hammer (Schmidt hammer) test, for which calibration is still related to the original Schmidt curve dating back

European Journal of Engineering Research and Science, 2020 A comparative analysis between Rebound Hammer and Pullout method in testing concrete was conducted in this study. Experimental analysis were carried out to compare the correctness between the two testing method in estimating the strength of concrete. Different cube (cubes of 175 x 175 x 175) samples were prepared using two mix designs of 1:2:4 and 1:3 ...

The Performance of Empirical Laws for Rebound Hammer Tests on Concrete Structures
Applied Sciences, 2022 The assessment of concrete compressive strength plays a key role in the analysis of the seismic vulnerability of existing buildings. However, the adoption of classical destructive tests is usually limited by their invasiveness, cost and time needed for the execution.

Robust Analysis of Various Measurement Uncertainty Parameters in Rebound Hammer Test
Indian Journal Of Science And Technology, 2023 Abstract Objective: The major objective of the proposed work is to determine the concrete’s expected compressive strength by evaluating the consistency of concrete using Rebound Hammer Test. Further, the determination of the quality of one component of the concrete relates to the quality of another component based on the concrete meeting criteria ...

An investigation of the possible extent of the re-spending rebound effect in the sphere of consumer products [PDF]
, 2002 A key method used to reduce the environmental impact of a product is to make it more energy efficient. Previous studies have found that the potential benefits from improved efficiency are often at least partially negated by increased use of the product.

Development of rating curves for concrete rebound hammer on concrete specimens from local aggregates [PDF]
, 1957 Frequently engineers find it imperative to determine the compressive strength of concrete as it exists in a structure. There are two methods of making this determination, either by a destructive or a non-destructive test.

Advanced Materials Technologies, EarlyView.Nano‐TiO2 and carboxylated cellulose nanofibers jointly regulate hydration‐product distribution in cementitious composites. Improved microstructural continuity and refined pore structure accompany enhanced strength and surface stability without a substantial increase in overall hydration.
