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 additional offsite testing. The new technology would remove the need for extensive offsite testing by allowing construction contractors to verify the concrete’s maturity on site. “Our sensors could help make better data-driven decisions to determine the construction schedule and improve the quality of concrete construction,” said Luna Lu, Purdue’s American Concrete Pavement Association professor of civil engineering, in a news release.
