Project description

The aim of this project is to develop a reliable in situ testing method to determine the quality of concrete for traffic opening by using piezoelectric sensors coupled with electromechanical impedance (EMI) to determine early age properties of concrete. The potential benefits of using this non-destructive testing (NDT) include 1) reducing pre-mature failure of concrete pavement, patching and other concrete structures; 2) determining optimal traffic opening time based on reliable data of concrete property; 3) enabling cost and schedule savings due to reduced testing samples and testing time; and 4) eliminating construction worker safety issues on the job site and accident rates in opening zones.
