Abstract

In this paper, initial results obtained from exploiting a time-varying electric field for imaging the internal reinforcing in concrete are presented. Both theoretical and experimental studies have been conducted to establish the feasibility of imaging both steel rebar and fibreglass reinforced plastic (FRP) rebar embedded within concrete. The system, based upon capacitive sensing, responds to minute changes in the dielectric properties of the medium in the proximity of the sensor. At the time of writing, the prototype system can image a 10 mm FRP rebar to a depth of 40mm.
