Assessing the Rebound Hammer Test for Rammed Earth Material [PDF]
Sustainability, 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]
Materials, 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.

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

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 ...
