Abstract
Self-sensing concrete consists of embedded conductive materials allowing enhanced electric conductivity for assessing mechanical properties. This thesis describes the design of a self-sensing concrete with steel fabrication waste and the detection of the electric responses during the cooling process from 115 °C. The thermal process is recorded using an infrared camera and the changes of the electric responses are correlated empirically. The thermal effect on the steel waste-modified concrete is the decrease in electric resistivity and to detect the change in resistivity, both voltage and current changes were investigated.The electric field measurement for thermal property correlations involves multi-physical phenomenon and an attempt is made in describing the multiphysics in theoretical sense. Also investigated is the effect of temperature rising due to the continuous electric current flow through the material.This study concludes that it is possible to correlate resistivity change to the thermal properties of the cooling concrete.
