It is described a laboratory investigation on the resistance to freezing and thawing of recycled aggregate concrete (RAC).Comparing with the natural aggregate concrete (NAC) in the weight loss,the dynamic modulus of elasticity decrease and the strength,it is found that RAC is as durable as NAC.Especially,the durability of RAC by the design method of increasing cement paste is the most durable among the three kinds,even more durable than NAC.According to the result of the experiment,the strength reduction is used as the criterion of the freeze-thaw durability of RAC,besides the weight-loss and the decrease of dynamic modulus of elasticity.

为了探讨再生骨料混凝土(RAC)的抗冻融耐久性能,选用三套配合比设计方案,即普通法、预湿水法和增浆法,通过冻融前后质量、动弹性模量和强度的对比研究,并与天然骨料混凝土(NAC)作对比。结果发现,加入引气剂后再生混凝土能达到甚至超过天然混凝土的抗冻性能,其中增浆法配制的再生混凝土的抗冻融性能最好;降低水灰比会提高抗冻性能;对于再生混凝土抗冻性能用质量损失和相对动弹性模量下降已经不能很好地衡量其抗冻性,引入强度损失这一指标更为合适。
