混凝土气泡结构和抗冻性的关系初探

摘要

通过对引气和非引气混凝土两阶段的试验，研究了引气剂如何改善混凝土抗冻性、含气量在多大时效果较好，以及不同的外加剂对抗冻性的影响，得出相关结论，从而为混凝土气泡结构与抗冻性关系的研究奠定基础。%Through testing the concrete at air void and non-air void stages, the paper discusses how to improves the frozen resistance and the best effect with certain amount of air void, and talks about the impacts of various admixtures upon the frozen resistance, and obtains relevant conclu- sions, so as to lay a foundation for studying the relationship between concrete air void structure and frozen resistance.
