摘要

通过试验研究了熔提不锈钢纤维对混凝土力学性能和抗弯性能的影响。共使用72个试样来确定纤维的最佳掺量和钢纤维增强混凝土的力学性能。12个全尺寸梁试件然后暴露于四点弯曲试验。本试验量化了熔体提取不锈钢纤维对梁的受弯性能的影响。在经受15000次疲劳荷载循环后，梁试件暴露于四点弯曲。对熔提钢纤维梁的疲劳前后抗弯性能进行了比较和讨论。

Mechanical flexural properties of concrete with melt-extract stainless steel fibres

An experimental study is performed to evaluate the effect of melt-extract stainless steel fibres on mechanical and flexural properties of concrete. A total of seventy-two specimens are used to determine an optimum fibre dosage and mechanical properties of plain and steel fibre reinforced concrete. Twelve full-scale beam specimens are then exposed to four-point bending tests. The effect of melt-extract stainless steel fibres on flexural behaviour of beams is quantified in this testing. A beam specimen is exposed to four-point bending, after being subjected to 15000 cycles of fatigue load. Pre- and post-fatigue flexural properties of beams with melt-extract steel fibres are compared and discussed.
