| Abstract: | Through the splitting tensile strength tests,the effects of strength grade of ordinary concrete(NC)and interface treatment methods on the interface bonding performance of hybrid fiber reactive powder concrete(HFRPC)and NC were studied.The results show that compared with the interface treatment methods of roughing,exposing aggregated and cutting groove,the splitting tensile strength of planting reinforcement HFRPC-NC specimen is the highest,which is 1.15~1.22 times the failure strength of NC specimen,and the failure mode is ductile failure.For the three interface treatment methods of roughing,exposing aggregated and cutting groove with different roughness,the splitting tensile strength of HFRPC-NC specimen can reach 70%~92%of the failure strength of NC specimen,and the splitting tensile strength increases with the increase of the interface roughness.The splitting tensile strength of HFRPC-NC specimens increases with the increase of NC strength grade. |
