概述干燥碳化对混凝土耐久性的影响问题,国内未查到有关资料,从国外文献资料来看,比较一致的结论是:混凝土灌筑后潮养几天,再在空气中干燥一定时间能提高其耐冻性。例如,据美国混凝土协会报导:“加气混凝土在初期潮养之后,应随即使之充分暴露干燥—个时期,以保证其最大的耐久性。”美国A·Y·C·Wong等人在 Summarize the effect of dry carbonation on the durability of concrete, the domestic did not find the relevant information, from foreign literature, the more consistent conclusion is: concrete pouring a few days after tide, and then dried in the air for some time to improve its Frost resistance. For example, according to the American Concrete Institute, “Aerated concrete should be allowed to fully expose to dryness for an extended period of time after the initial tide, to ensure maximum durability.” USA Wong Wong et al.
