| 摘 要： | 未经预养的负温防冻剂混凝土在受冻前未能形成很好的早期结构，内部易损伤，不利于后期抗冻融－碳化耐久性。有一定预养期的负温防冻剂混凝土，特别是有高效减水剂组分的，会显著提高抗冻融－碳化耐久性能。

| Abstract: | The non-precuring concrete mixed with negative temperature freeze-proof agent,can hardly to form a good early stage structure before freezing period,therefore its internal constitution could be easily damaged and its anti-freezing-thawing property and carbonized durability would be eventually hampered.Within a certain period of concrete curing,the negative temperature concrete mixed with freeze-proof agent,especially with high effective dewatering agent,would greatly promote the concrete' s anti-freezing-thawing property and carbonized durability. |

| Keywords: | concrete mixed with negative temperature freeze-proof agent durability winter construction |
