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 ...

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 ...

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, ...

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 ...

American Association of State Highway and Transportation Officials’ Committee on Materials and Pavements approves Purdue-invented method as a national standard for estimating concrete strength WEST ...

While Facebook parent company Meta has drawn attention for its efforts to create a virtual “metaverse,” the company is also focusing on the impact of its real-world buildings. Meta is working with ...

The 3D-printed concrete barracks requires a crew of only three trained workers during construction, though for continuous printing, about three shifts of crews are required to avoid burnout. Photo by ...
