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, ...

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 ...

When choosing a method for monitoring the compressive strength of concrete, it’s important for project managers to consider the impact each technique will have on their schedule. While some testing ...

Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...

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 ...
