✦ Synopsis
The contact electrical resistivity between carbon fiber and cement paste was found to decrease with increasing bond strength and to increase during fiber pull-out from the paste. Both effects are due to the interfacial voids, which are electrically insulating. Evidence is provided in support of the feasibility for the volume electrical resistivity increase during tensile loading of carbon fiber reinforced cement to be due to fiber pullout.
