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 ...

Researchers have, for the first time, used a 'micropillar compression' technique to characterize the micro-scale strength of cement, allowing for the development of cement with desirable strength ...

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 ...

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 ...
