钢纤维类型和分布形式对混凝土抗压性能的影响

Experiment Study on Compression Behavior of Steel Fiber Reinforced Concrete

以几种不同类型钢纤维增强混凝土的抗压性能试验研究为基础,讨论了钢纤维掺量、分布形式以及钢纤维类型对混凝土抗压性能的影响。试验结果表明,随钢纤维掺量的提高,钢纤维增强混凝土的抗压性能有不同程度的提高;因钢纤维类型不同,对混凝土的增强效果各异,其中弓形钢纤维对抗压强度的增强效果较好,哑铃形钢纤维对延性比提高率的影响较大;钢纤维分布形式的不同对混凝土抗压强度也有一定影响。

Concrete reinforced with different kinds of steel fibers is studied experimentally. The effect of content, orientation, and type of steel fibers on concrete is discussed. Test results show that compression behavior of concrete is enhanced with the increase of the content of steel fibers, the effect of different steel fiber on concrete is diverse, the effect of the deformed steel fibers on compressive strength and the dumbbell steel fibers on ductile effectiveness is better than that of the others. Compressive strength of concrete was also influenced by the orientation of steel fibers.
