摘　　要：通过对43组129个尺寸为100 mm×100 mm×100 mm的混凝土立方体试件进行试验研究,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性能的变化规律,探讨了钢纤维对混凝土抗压强度的影响机理。试验结果表明,混凝土基体强度等级较高时,钢纤维对碳化后混凝土抗压性能改善比较显著。Through the experimental research on the 129 concrete specimens with the size of 100 mm × 100 mm × 100 mm,the volume fraction of steel fiber, the grade of concrete strength and different carbonization time were taken as variable parameters. This paper studied the influence of the volume fraction of steel fiber, the grade of concrete strength and different carbonization time on the compressive strength of steel fiber reinforced concrete. Furthermore, the reinforced mechanism of the steel fiber reinforced concrete under the action of carbonization was discussed. The study results showed that when the grade of concrete strength is higher,it is more obvious for steel fiber to improve the compressive strength of steel fiber reinforced concrete.
