Abstract:The mechanical property of mode I concrete/epoxy interface was studied by wedge split test method, and the traction-separation law was obtained. Whether the silane coupling agent was able to improve the performance of concrete/epoxy interface under NaCl solution was also analyzed. The results show that both the ultimate bond strength and the fracture energy decrease exponentially with soaking duration. Under mode I loading, the failure mode of the control specimen is tensile failure of the concrete. With the increase of soaking duration, the failure mode of the interface specimen was gradually turned into adhesive failure along the concrete/epoxy interface. The performance of the concrete/epoxy interface can be improved by the application of silane coupling agent. © 2018, Central South University Press. All right reserved.
