This document summarizes a civil engineering student project evaluating factors and remedies for bonding between old and new concrete layers. Students will conduct slant shear and flexural tests on molds with different surface treatments and bonding materials. The tests will assess bond strength. Surface roughness, epoxy, and wire mesh will be evaluated as potential remedies to strengthen bonding. Test results will show the effect of concrete overlays on the overall strength of members compared to monolithic members.
