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 ...

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 ...

Some basic NDT techniques utilized to assess concrete structures include:Once concrete has hardened, it is important to determine whether the final structure is suitable for its designated use. To do ...

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 ...

Maturity and compressive strength of concrete is tested through both destructive and non-destructive methods. Destructive test involve damaging some of an element or the structure. Some would like to ...

This appendix contains short descriptions of different certification programs related to materials sampling and testing that were referenced in the literature review. The programs are listed in ...
