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, ...

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 ...

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 ...

Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

Purdue University professor Luna Lu holds the REBEL concrete strength sensing system, which her lab invented to improve estimates of in-place strength of concrete structures. As a beta product of ...

New research shows steel I- and T-sections inside concrete beams can offset shear loss from web openings—enhancing safety in ...

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 ...
