Abstract
In order to study the impact resistance performance of ultra-high performance concrete (UHPC) slab with basalt fiber, the experiment of six concrete slabs was conducted. The following factors were considered in this study: different basalt fiber types, steel mesh, and water-based epoxy mixture. The drop weight method was used, and the effect of various factors on the impact resistance performance of ultra-high performance concrete slab with basalt fiber were investigated in details. The test results showed that the basalt fiber could significantly increase the impact resistance of UHPC slab. The basalt fiber with a long length after cracking was more significant to improve the impact resistance performance of UHPC slab. The basalt fiber, steel mesh, and water-based epoxy can significantly improve the impact resistance and energy absorption capacity of UHPC slab. The ductility coefficient of UHPC slabs are less than 0.6.
