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 ...

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 ...

Concrete is the most used construction material in the whole world. More than that, behind water, it’s the most used material, all categories combined. Worldwide, about 10 billion tons of concrete are ...

Simpson Gumpertz & Heger’s (SGH) Applied Science & Research Center recently received ISO/IEC17025 accreditation from the American Association for Laboratory Accreditation (A2LA) for several concrete ...

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 ...

The size of designs continues to grow and IC manufacturers are pushing for higher test quality, especially in mission-critical applications such as transportation and medicine. More advanced nodes ...
