Site-Test Research on Shearing Capacity of Bonding Interface Between New and Old Concrete

摘要

Base on a practical project, the site-test Research on s Capacity of Bonding Interface Between New and Old Concrete was carried out with three different disposal ways, which is Roughening, slotting and planting bar. The test process and phenomenon were described, the conclusion is that Planting bar is a more effective way to improve the bearing capacity between the new and old concrete surface.
