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 ...

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 ...

Concrete slabs-on-ground develop curl when a moisture or temperature gradient exists between the top and bottom surfaces of the slab. As the exposed top surface dries and shrinks relative to the ...

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 ...

WEST LAFAYETTE, Ind. – WaveLogix, a startup technology company that is commercializing an Internet of Things sensing system for infrastructure monitoring, has received a six-month SBIR Phase I grant ...

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 ...

Researchers have created a graphene-enhanced, 3D-printable concrete that improves strength and reduces carbon emissions by 31%, advancing sustainable construction. Researchers from the University of ...

This appendix contains short descriptions of different certification programs related to materials sampling and testing that were referenced in the literature review. The programs are listed in ...

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 ...
