Abstract: In order to research the effect of basalt fiber in reactive powder concrete, the splitting tensile strength test and the cube compressive strength test of basalt fiber reinforced reactive powder concrete with the parameters like the content of the fiber, the length of fiber, the water-binder ratio of reactive powder concrete and the age of the concrete were conducted.The results show that for the reactive powder concrete mixed with basalt fiber whose length is 12 mm, the best water-binder ratio is 0.22 and the best volume content is 0.10%, and the splitting tensile strength improves 38.53% compared to the reactive powder concrete without fiber.For the reactive powder concrete mixed with basalt fiber whose length is 6 mm, the best volume content is 0.05%, and the splitting tensile strength improves 27.16% compared to the reactive powder concrete without fiber.
