| 摘 要： | 研究了混杂纤维(钢纤维和聚丙烯纤维)对道路混凝土力学性能的影响。钢纤维以体积掺量为0.6%~1.1%,聚丙烯纤维体积掺量为0.1%~0.2%。纤维总体积掺量分别为0.8%、1.0%和1.2%。研究表明,混杂纤维对混凝土的抗压强度、抗折强度和劈拉强度都有不同程度增强作用,其中对抗折强度增强作用最为明显,其次是劈拉强度和抗压强度。两种不同性质的纤维同时加入可以产生混杂效应,其增强作用优于掺入单一纤维时的增强作用。 |
| 关 键 词： | 混杂纤维 增强 混杂效应 道路混凝土 力学性能 |

| Abstract: | The influences of hybrid fiber(steel fiber and polypropylene fiber) on the mechanical properties of pavement concrete were investigated in this paper.The volume content of steel fiber is from 0.6% to 1.1%,and that polypropylene fiber is 0.1% and 0.2%.The total content of fibers is 0.8%,1.0% and 1.2%.The results indicate that the compressive strength,flexural strength and splitting tensile strength can all be improved to some extent,and the flexural strength is improved most obviously.The addition of two dif... |
