摘要
超高性能混凝土是一种具有超强耐久性、超高强度的特殊混凝土。文章研究了不同钢纤维掺量对超高性能混凝土的工作性能和力学性能的影响,结果表明,钢纤维会导致细骨料UHPC流动性降低,并且流动性均随着掺量的增加而降低更多,同时钢纤维可以提高抗压强度和抗折强度,并均随着掺量的增加而增大。
Ultra High-Performance concrete(UHPC) is a kind of special concrete with super durability and super strength. Effects of different steel fibre dosages on the working performance and mechanical properties of UHPC were studied. Results showed that the use of steel fibre will lead to a decrease of the fluidity of fine aggregate UHPC, and the fluidity decreases with the increase of its dosage. Steel fibre also can improve compressive strength and flexural strength, and the two strengths increase with the increase of the dosage of steel fibre.
