摘要
利用有50年龄期的废弃混凝土破碎所得骨料作为再生混凝土的粗骨料,并分别以25%、50%、75%及100%的掺入百分比配制再生混凝土,探讨再生混凝土的抗冻耐久性,即抗冻融循环的能力。结果表明,用以上方法配制的再生混凝土基本上能符合抗冻耐久性的相关规定,抗冻融循环的能力能达到一般工程的要求。
It is an laboratory investigation on the resistance of freezing and thawing of recycled aggregate concrete （RAC）.The 50-year-old recycled coarse aggregate were used in the RAC,using the replacement percent of 0%, 25%, 50%, 75% and 100%.It is found that the standard of the durability of freezing and thawing was satisfied,and the RAC can be used in the normal projects.
