摘　　要：对负温养护、－６～－２０℃变负温养护、有覆盖自然变负温养护三种养护制度下，掺混合材负温防冻剂混凝土强度发展规律的试验表明，适量混合材和高效防冻剂的复合使用，既能满足冬期施工混凝土早期强度要求，又能较大幅度提高后期强度。There are three kinds of concrete curing method namely:negative temperature curing ,-6～-20℃ various negative temperature curing, and under natural cover various negative temperature curing.Through all three kinds of concrete curing experiments on strength of negative temperature concrete mixed that,with compound material freeze-proof admixture,it is demonstrated that,with proper amount application of compound material admixture and high effective freeze-proof agent,there would be not only a great satisfaction in winter construction of an early strength concrete,but also an extensive promotion of the final strength of concrete.

关 键 词：混合材 负温混凝土 强度 冬期施工
