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 ...

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 ...

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 ...

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 ...

A shortage of skilled labor continues to be the dominate issue in the construction industry, and rightfully so. However, delays in construction schedules have always been a thorn in the side of ...

Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

Controls' Automax 5 series of Concrete Testing equipment features a fully automatic test cycle with a closed loop retraction. The load/time graph and the gradient are displayed in real time, while the ...
