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 ...

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 ...

This innovative IoT-ANN framework allows for non-destructive concrete strength assessment, improving accuracy and ...

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 ...

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 ...

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 ...

Sensors from the WaveLogix REBEL Concrete Strength Sensing System, seen here at a road construction site in Tennessee, help detect road strength in real-time. Submitted photo Sensors that could change ...

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 ...

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 ...
