Abstract: Ultra-High-Performance Fiber-Reinforced Concrete(UHPFRC) has been applied to various fields of the construction industry, especially high-rise buildings, long-span bridges, submarine tunnels, etc.,due to its excellent mechanical properties and durability.For this, the effects of fiber type(basalt fiber, steel fiber, and PVA fiber) and their amount(0,0.5%,1.0%,2.0%) on the mechanical properties(uniaxial compressive strength, elastic modulus) and the anti-permeability performance(permeability) of UHPFRC were studied.The research results showed that:(1) The mechanical properties and the anti-permeability performance of UHPFRC composed of different fiber types are different.The mechanical parameters of UHPFRC with steel fiber are significantly higher than those of UHPFRC with basalt fiber and PVA fiber.The permeability of UHPFRC with PVA fiber is significantly higher than that of UHPFRC with steel and basalt fiber.(2) Within the scope of this study, the uniaxial compressive strength and elastic modulus of UHPFRC gradually increase with the increasing of steel fiber content, and the overall mechanical parameters are greater than those of the non-fiber concrete.With the increasing content of basalt fiber and PVA fiber, the uniaxial compressive strength and elastic modulus of UHPFRC decrease gradually.(3) With the increasing content of PVA fiber and basalt fiber content, the permeability of UHPFRC gradually increases, while the permeability of UHPFRC gradually decreases with the increasing of steel fiber content.
