摘要：

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 resistivity slightly, but does not affect the linear correlation, which provides a nondestructive method for bond strength assessment.
