钢纤维掺量对聚合物改性混凝土抗冻融性能的影响研究

Research of Influence of Steel Fiber Content on Freeze-thaw Resistance of Polymer-modified Concrete

钢纤维聚合物改性混凝土显示出良好的物理力学性能,具有十分广阔的工程应用前景。文章通过室内试验的方式,探讨了钢纤维掺量对钢纤维聚合物改性混凝土抗冻融性能的影响,获得相关参数的变化规律。结合试验结果,建议在工程设计和应用中选择1%的钢纤维掺量,不仅可以获得较好的抗冻融性能,还可以有效控制施工成本。

Steel fiber polymer-modified concrete shows excellent physical and mechanical properties.It has a very broad prospect of project application.In the paper,the influence of steel fiber content on the freeze-thaw resistance of steel fiber polymer-modified concrete is discussed by means of laboratory tests.The change rules of relevant parameters are obtained.The test results are combined.It is suggested to choose 1%steel fiber content in project design and application,thereby not only obtaining better freeze-thaw resistance,but also effectively controlling the construction cost.
