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

The bond strength between carbon fiber and cement was enhanced by oxidizing chemical treatments, with ozone treatment giving the greatest effect. The effect was accompanied by an increase in the electrical contact resistivity of the interface. These effects are mainly attributed to oxygen-containing
