通过在保温混凝土中加入0、0.5%、1%、1.5%、2%和2.5%六种钢纤维掺量,对混凝土进行不同龄期的试验,分析在不同钢纤维的掺量、NS掺量和不同龄期对钢纤维保温混凝土的抗压强度影响。试验结果表明:在保温混凝土中单掺钢纤维时对混凝土的抗压强度影响较小,而在混凝土中同时掺入钢纤维和NS时混凝土抗压强度极大提高,因此在保温混凝土中同时加入钢纤维和NS后对混凝土的抗压强度有极大改善。
By adding 0.5%, 1%, 1.5%, 2% and 2.5% steel fiber into insulation concrete, the concrete was tested at different ages to analyze the influence of different steel fiber content, NS content And different ages on the compressive strength of steel fiber concrete insulation. The test results show that the compressive strength of concrete is little affected when single steel fiber is added into concrete, while the compressive strength of concrete is greatly increased when steel fiber and NS are mixed in concrete at the same time. Therefore, The compressive strength of concrete after steel fiber and NS has been greatly improved.
