The figure 8 new and old mortar tensile test method is used for bond strength of adhesive mortar, bonding material in different mixture ratio under conditions of adhesive properties of different bonding materi-als, and the variation law of tensile strength is obtained as well. The test results show that carbon nanotubes reinforced cement mortar performance is good, which is suitable as an interface between new and old concrete repair materials.
