So that it may be certain that a concrete specimen’s mechanical properties reach the strength and deflection imperatives for its intended use, concrete specimens with specific dimensions are prepared, ...

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 ...

As a foundational building material, concrete must exceed quality and strength expectations. This means rigorous testing throughout the construction process. Concrete is the most commonly used ...

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 ...

If structural engineers have their way, building codes will take a leap forward in the next couple of years to allow the use of higher-strength 80-ksi reinforcing steel in concrete shear walls in high ...

A concrete-testing laboratory faked results for a LaGuardia Airport control tower, the new Yankee Stadium, the Lincoln Tunnel and more than a dozen other projects around the city, creating thousands ...
