摘要
研究了不同规格及掺量的钢棉对超高性能混凝土(UHPC)工作性和力学性能的影响。结果表明:钢棉的掺入降低了UHPC的流动性和抗拉性能,但合适规格及掺量的钢棉可显著提升UHPC的抗压强度和抗折强度。
The influence of different specifications and dosages of steel wool on the workability and mechanical properties of ultra-high performance concrete(UHPC)was studied.The results show that the incorporation of steel wool reduces the fluidity and tensile properties of UHPC,but the compressive strength and flexural strength of UHPC can be significantly improved with appropriate specification and dosage of steel wool.
