【摘要】 旨在研究掺有防冻剂的再生混凝土的抗冻性能,即负温养护对掺有YJ-4型防冻剂的再生混凝土质量的影响,质量用抗压强度表示.同时研究了掺有YJ-4型防冻剂的再生混凝土在标准条件养护下的强度,以及抗冻融循环能力,并与未掺任何外加剂的再生混凝土进行了比较.更多还原

【Abstract】 In this paper,the frost resistance of recycled concrete with antifreeze and the effect on the quality when it was maintained in sub-zero temperature were discussed.Its mechanical capability was indicated by compressive strength.The compressive strength after being cured in standard condition for 28 days and the ability to resist the freezing-thawing cycles were studied as well.At last,comparison was made with the recycled concrete without any admixture.更多还原
