文章定性分析讨论了水泥混凝土中微观气泡与宏观抗盐冻性能的关系。根据试验结果得出结论:C30混凝土按标准养护比按规范养护的抗盐冻能力明显高,其气泡平均半径基本一致,但气泡总面积相差约一倍,说明气泡面积对抗盐冻性能影响很重要;在施工时应根据环境情况调整养护方案,增加混凝土抗盐冻性能;低强度与较高强度混凝土在盐冻过程中气泡的发育与破坏的过程不同,结果也不同,高强度混凝土抗盐冻性能远高于低强度混凝土。
The article qualitatively analyzes and discusses the relationship between microscopic bubbles and macroscopic salt frost resistance in cement concrete. According to the test results, it is concluded that the freezing resistance of C30 concrete with standard curing ratio is significantly higher than that of the standard curing one. The average bubble radius is basically the same, but the total bubble area is about double, indicating that bubble area is very important to the anti-freezing performance ; In the construction should be based on environmental conditions to adjust the conservation program to increase the salt resistance of concrete performance; low strength and high strength concrete in salt water during the process of bubble development and destruction of different results are also different, high-strength concrete anti-salt Performance is much higher than low-strength concrete.
