Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...

The use of the non-destructive testing methods for determining the compressive strength of high performance concrete ensures high quality. Compressive strength test results are mainly used to ...

Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...

As a foundational building material, concrete must exceed quality and strength expectations. This means rigorous testing throughout the construction process. Concrete is the most commonly used ...

Defects can occur naturally during composite fabrication, and damage can be induced by impacts in service, but these tend to be relatively uncontrolled events. It was desired to induce an easily ...
