To receive a stipend, individuals must be high-earners who can work remotely and are willing to relocate to West Lafayette.

Engineers at Purdue University in West Lafayette, Ind. have developed slab-embedded sensors that can safely speed up a construction timeline by determining concrete strength directly onsite in real time. Their technology removes the need for extensive offsite testing by allowing contractors to verify concrete maturity onsite.

The sensors she and her team have developed can instantly measure concrete stren...

By Dian Schaffhauser 02/11/21 Engineering researchers at Purdue University have come up with sensors that can determine concrete strength onsite in real-time, and they're testing it right on campus. The hope is that the technology will help builders speed up their construction timelines safely. According to a campus article, concrete mix designs are tested offsite for "compressive strength" before their use in a construction project. Once the testing is done and the mixes vetted for use, they can't be changed without additional testing. The new sensors would eliminate the need for offsite tes...

Typically, concrete mix designs require testing before implementation in a construction project. Once those mixes have been vetted for use, the mix design cannot be altered without ...

The Research in Concrete Sensor Technology Pushing construction technology further to get real time data from concrete sensors, Purdue researchers have been working on a years-long project to investigate the value of integrating concrete sensors with the internet of things. February 3, 2021 Purdue University engineers have developed sensors that could safely speed up a construction timeline by determining concrete strength directly onsite in real-time. Purdue’s American Concrete Pavement Association Professor of Civil Engineering speaks with editor Jonathan Kozlowski on the recent research ...
