摘　　要：作为水工混凝土的掺合料是废旧轮胎资源化利用的重要途径,具有重要的经济意义和生态价值。文章通过室内试验的方式,探讨分析废旧轮胎橡胶粉细度对水工混凝土抗冻融性能的影响。试验结果显示,当废旧轮胎橡胶粉为100目时可以获得最佳抗冻性能,推荐在工程设计中采用。As an admixture of hydraulic concrete, it is an important way to recycle waste tire and has important economic significance and ecological value. In this paper, the influence of the fineness of waste tire rubber powder on the freeze-thaw resistance of hydraulic concrete is discussed and analyzed by means of laboratory test. The test results show that when the waste tire rubber powder is 100mesh, the best freezing resistance can be obtained, which is recommended to be used in engineering design.
