The Performance of Empirical Laws for Rebound Hammer Tests on Concrete Structures

open access: yesApplied Sciences (Switzerland), 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 Influence of the Rebound Hammer Test Location on the Estimation of Compressive Strength of a Historical Solid Clay Brick

open access: yesSolids, 2023
This paper presents the study of a two-hundred-year-old, demolded solid clay brick using the rebound hammer test for the estimation of the compressive strength. During the test, the location and face type influence on the rebound values are monitored and

Assessing the Rebound Hammer Test for Rammed Earth Material [PDF]

open access: yesSustainability, 2017
Rammed-earth (RE) is a construction material manufactured from the soil. The soil is compacted at its optimum water content, inside a formwork to build a monolithic wall. RE material is attracting renewed interest throughout the world thanks to its sustainable characteristics: low embodied energy, substantial thermal inertia, and natural regulator of ...

Characteristic Curve and Its Use in Determining the Compressive Strength of Concrete by the Rebound Hammer Test. [PDF]

open access: yesMaterials (Basel), 2019
During the construction of concrete structures, it is often useful to know compressive strength at an early age. This is an amount of strength required for the safe removal of formwork, also known as stripping strength. It is certainly helpful to determine this strength non-destructively, i.e., without any invasive steps that would damage the structure.

Factors influencing the performance of rebound hammer used for non-destructive testing of concrete members: A review

open access: yesCase Studies in Construction Materials, 2021
Non-destructive testing (NDT) has a vital role in finding surface hardness of concrete members. B-Proceq curve can calculate the concrete strength by providing statistical correlations between the destructive and the non-destructive strength.

Repeatability of concrete rebound hardness using comprehensive statistical analysis

open access: yesJournal 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.
