In this paper, the shear properties of the interface between polyvinyl alcohol fiber cement-based composites (pva-ecc) and concrete with different roughness are studied. The test results show that: 1. Z-type interface can effectively improve the shear performance of pva-ecc and old concrete; 2. With the increase of roughness, the slip peak value increases, and the horizontal extension section under failure shear stress is also longer; 3. The shear strength of the four types of interfaces is directly proportional to their roughness, but lower than the shear strength of the concrete itself.
