Concrete is an essential construction material that is used globally. Combining coring and rebound surveys provides the most efficient and cost-effective method of assessing in situ concrete strength, ...

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 ...

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 ...

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 ...

Using the principles of light, scientists have discovered a new way to measure the strength of modern forms of concrete -- giving industry a better way to understand when it could fracture. Using the ...

Following seven years of research, approval of this Purdue-developed technique as a standard by the American Association of State Highway and Transportation Officials is an initial step toward the ...
