Abstract
The steel bars with good electrical conductivity were used as two kinds of electrodes in the making of carbon fiber (CF) electrically conductive concrete for heating. The results of the pertinent experiments illustrate the design is viable. The change in electrical resistivity over three years’ hydration time was studied when steel bars were used as lateral face electrodes and top bottom surface electrodes respectively. The temperature rise test was conducted to verify the heating properties of two kinds of concrete. Not only the study can reduce the CF volume content of electrically conductive concrete for heating to 0.58% or 0.36% according to different design, but also it will enhance the carrying capacity of the concrete roadway for heating.
