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 ...

So that it may be certain that a concrete specimen’s mechanical properties reach the strength and deflection imperatives for its intended use, concrete specimens with specific dimensions are prepared, ...

When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...

Although failure of material is not the only reason for bridge failures, it is a vital step for choosing the correct materials, the analysis of bridge design, and construction testing. Bridge members ...

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 ...

President, Wyoming Test Fixtures Inc. Unlike metals and plastics, for which tensile and compressive properties are the same or very similar, unidirectional composites exhibit significantly different ...
