| 摘 要： | 通过对30个立方体试块抗压强度试验,分析了钢纤维对普通混凝土的增强作用;通过对30个小梁试件三分点加载抗折试验,研究了体积率对钢纤维混凝土(SFRC)荷载-挠度关系及荷载-极限应变关系的影响.在脆性基体中掺入钢纤维,有效地提高了复合材料承受荷载时阻止裂缝引发与扩展的能力,达到对混凝土的增强效果,尤其是对于抗折强度的增强作用,使混凝土的破坏形式由脆性破坏变为塑性破坏.

| Abstract: | Based upon the experimental results obtained from cube crushing strength test of 30 blocks and bending strength test of 30 short beams,the effects of the steel fiber volume ratio on the strength enhancement of concrete,the relationship between load and flexibility and that between load and limiting strain of SFRC are studied.Incorporation of steel fiber into brittle parent material can effectively prevent the initiation and extension of flaw,and hence enhance the concrete strength,particularly the bending strength,which makes the failure formation of concrete turn from brittle to plastic. |
