Detect3C: Advancing the Assessment of Concrete Chloride Content Through Non-Destructive Techniques

Chloride infiltration causes corrosion in steel reinforcements, compromising concrete structures’ integrity and longevity. Traditional assessments using invasive core sampling and laboratory testing are time-consuming, disrupt traffic, and offer limited spatial insight, hindering effective maintenance strategies. X-wave Innovations, Inc., in collaboration with the University of Nebraska-Lincoln, is developing Detect3C for rapid, non-destructive concrete chloride assessment. This technique accurately profiles chloride content, significantly reducing field work and resource demands, while providing comprehensive data across and through entire bridge deck with minimal traffic disruptions. Phase I demonstrated the feasibility of our approach and Detect3C’s effectiveness. In Phase II, we will develop a fully-functional Detect3C prototype and further validate its capability for rapid, non-invasive, comprehensive assessment of bridge deck chloride content.
