The bond strength and contact electrical resistivity between steel rebar and concrete were found to be linearly related, due to an interfacial phase of high volume resistivity that helps the bonding. Acetone washing of the rebar increases the bond strength slightly and decreases the contact resistiv

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
