摘要
本文通过对试验结果的分析研究,探讨了钢纤维体积率、长径比,基体水灰比,水泥用量,砂率、骨料粒径等因素对钢纤维混凝土抗压强度的影响以及抗压强度的尺寸效应,从机理上分析钢纤维对混凝土抗压性能的增强作用,有关试验方法的建议和结论已列入我国的《钢纤维混凝土试验方法标准》。
By analytic study of the experimental results,the paper has researched the infulence upon the ompressive trength of SFC by fibre volume fraction,fibre aspect ratio,matrix water ce-ment radio,cement content,sand adio,aggregate diameter,and so on.The size effect on thecompressive strength of SFC has also been discussed.The einforced effect which is made bysteel fibre to the compressive behavior of concrete has been analysed from the echanism.The proposal about the experimental method and conclusion of SFC has been adopted byChinese tandard f the experimental method of SFC.
