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 ...

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 ...

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 ...

Backed by 22,000+ Overlay Projects of Experience, Independent Laboratory Testing, and More Than 500 Five-Star Reviews ...

Not all damage to a load-bearing structure is immediately apparent. So how do civil engineers find out that a bridge or a large hall is no longer safe? Many clues form a picture. Concrete structures ...

New analysis explains how outdated concrete testing slows road and bridge projects, and what Iowa's specification ...

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 ...
