摘要:
以钢纤维体积率、钢纤维类型、再生粗骨料处理方式以及试件尺寸作为参数,通过与钢纤维天然混凝土对比,探讨钢纤维对再生混凝土抗压性能的影响.试验结果表明:钢纤维再生混凝土抗压强度略低于钢纤维天然混凝土,钢纤维的加入可以在一定程度上提高再生混凝土的抗压强度,钢纤维再生混凝土立方体抗压强度的尺寸效应系数与钢纤维天然混凝土差别不明显.根据对试验数据的统计分析,铣削型钢纤维(MF)对天然混凝土抗压强度的影响系数为0.25,对预湿水再生混凝土抗压强度的影响系数为0.35,钢纤维对再生混凝土的增强效果优于天然混凝土.
Abstract:
Taking the volume rate of steel fiber, steel fiber type, treatment method of recycled coarse aggregate and specimen size as parameters, the influence of steel fiber on the compressive performance of recycled concrete was discussed by comparing it with steel fiber natural concrete. The test results show that the compressive strength of steel fiber recycled concrete is slightly lower than that of steel fiber natural concrete, and the addition of steel fiber can improve the compressive strength of recycled concrete to a certain extent, and the size effect coefficient of the cubic compressive strength of steel fiber recycled concrete is not significantly different from that of steel fiber natural concrete. According to the statistical analysis of the test data, the influence coefficient of milled steel fiber (MF) on the compressive strength of natural concrete is 0.25, and the influence coefficient on the compressive strength of pre-wet water recycled concrete is 0.35, and the reinforcement effect of steel fiber on recycled concrete is better than that of natural concrete.
