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 ...

Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

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 ...

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 ...

Hollow Glass Microspheres are inorganic, nonmetallic spherical materials created by specific processes, commonly with diameters in the range of 10 to 250 μm and wall thicknesses of 1 to 2 μm (Figure 1 ...
