摘　　要：通过对普通混凝土和再生混凝土遭受一次冻结后的冻害情况进行分析和比较,分掺加外加剂和未掺外加剂两种情况分别进行的。比较后分析再生混凝土与普通混凝土在抗冻性能方面的差异和联系,并阐述产生差异的原因以及外加剂对各自抗冻性能的影响。Analyzed and compared the frostbite situation of recycled concrete and normal concrete suffering one-time freezing through experimental study.The experiment was divided into two kinds of situation ,the one was for concrete without admixture and the other was for concrete adding admixture.Then analyzed the anti-frozen performance connection and discrepancy of the two kinds of concrete.At last, we expounded the reason that produced discrepancy and how admixture influences the anti-frozen performance of concrete.

关 键 词：抗冻性能 再生混凝土 普通混凝土 防冻剂
