摘要
含气量对混凝土性能的影响非常复杂。以铁路工程高性能混凝土桩基工程为例,通过调整引气剂掺量来控制混凝土中的含气量,测试了含气量对混凝土抗硫酸盐侵蚀性能的影响。结果表明在实际工作中应控制适宜的含气量。
The influence of air content on concrete performance is very complex. Taking the high performance concrete pile foundation project of railway engineering as an example, the air content in concrete is controlled by adjusting the amount of air entraining agent, and the effect of air content on the sulfate corrosion resistance of concrete is tested. The results show that appropriate gas content should be controlled in practical work.
