摘　　要： 通过对50组150个100mm×100mm×100mm和25组75个100mm×100mm×400mm的混凝土试件进行试验研究,以钢纤维体积率、混凝土强度等级和碳化龄期为变量,研究了不同体积率、不同强度等级的钢纤维混凝土在不同碳化龄期下抗压强度、劈拉强度以及抗折强度的变化规律,探讨了碳化钢纤维混凝土中钢纤维的增强机理,为钢纤维混凝土耐久性设计和分析提供试验依据,以完善和发展钢纤维混凝土理论,促进钢纤维混凝土这种高性能复合材料的工程应用。 In the carbonization experiment, the concrete strength, the volume fraction of steel fiber, strength degree and carbonization time were taken as variable parameters. Through the carbonization experiment of 150 concrete specimens with the size of 100mm ×100mm × 100mm and 75 concrete specimens of 100mm × 100ram × 400mm, the influential law of the grade of concrete strength, the volume fraction of steel fiber and the carbonization time on the compressive strength, splitting strength and rupture strength of steel fiber reinforced concrete are studied. The reinforced mechanism of steel fiber reinforced concrete upon the carbonization property was discussed. The research results can offer useful experimental data for design and analysis of durability property. It is also useful for the theory of steel fiber reinforced concrete to improve and spread its application.
