摘要
在再生混凝土施工中,掺加一定量的纤维可以有效改善其物理和力学性能,具有重要的工程应用价值。文章通过室内试验的方式,探讨了混掺钢纤维和聚丙烯纤维对再生混凝土力学性能的影响。结果显示,混掺纤维和单掺纤维相比,在提高再生混凝土力学性能方面的作用更为明显。结合试验结果,建议在工程应用中选择钢纤维和聚丙烯纤维的体积掺量为1:1,总掺量为0.4%的混掺方案。
In recycled concrete construction,adding a certain amount of fiber can effectively improve its physical and mechanical properties,which has important engineering application value.In this paper,the effects of mixed steel fiber and polypropylene fiber on mechanical properties of recycled concrete were studied by laboratory test.The results show that the mixed fiber plays a more significant role in improving the mechanical properties of recycled concrete than the single fiber.Combined with the test results,it is suggested to choose the mixing scheme with steel fiber and polypropylene fiber volume content of 1:1 and total content of 0.4%in engineering application.
