摘要：研究了使用混凝土预拌料和配套的钢纤维浇筑的超高性能纤维混凝土材料(UHPFRC)的抗压及抗弯性能。材料立方体抗压强度平均值在标准热水浴养护后达到165MPa；测试了两个基于此材料的UHPFRC配筋板条的抗弯承载力。试验结果表明，采用开孔截面且不使用箍筋的试件抗弯承载力仅比实心且配置抗剪钢筋的试件低10%。考虑到材料使用、构件自重和钢筋加工成本，超高性能空心配筋板的结构形式更为经济合理。 Abstract: The compressive strength and flexural strength of the Ultra-high performance fiber reinforced concrete slabs made from premix material and steel fibers are studied. The cube compressive strength reached beyond 165MPa after the standard hot water curing treatment. Two steel rebar reinforced slab strips are tested under flexural loading. The load capacity of the S2 specimen with circular hollow section without any shear reinforcement is only 10% lower than that of the S1 specimen, which is designed with solid section and shear reinforcement. Considering the amount of material, the self-weight of the deck system, and the cost associated with the rebar cage preparation, the ultra-high performance fiber reinforced hollow reinforced concrete slab is regarded as a more rational and economical solution.
