Abstract:A passive, wireless sensor has been developed at the University of Texas at Austin to monitor the insitu conductivity of concrete within civil infrastructure systems. Electrical conductivity is one possible indicator of corrosion of embedded reinforcement and thereby provides information on structural performance. The sensors would be attached to the reinforcement cages before placement of the concrete and interrogated as part of a routine inspection over the service life. A new sensor design, a non-contact co… Show more
