铜川市水厂工程冬季混凝土施工措施研究

Study on Concrete Construction Measures in Winter for Project of Tongchuan Water Factory

在寒冷地区进行冬季混凝土施工,须采取低温保护的工程措施,才能使混凝土结构早期避免受冻,不出现裂缝。结合铜川市水厂工程项目,对冬季混凝土施工的机口倾出温度,养护时间等进行了研究,并提出了冬季混凝土施工的工程措施。分析表明,混凝土拌和物的最终温度为11.2℃,混凝土出机口温度为9.4℃,在冬季暖棚内养护8 d可达到标准。工程建成后,经过观察未出现裂缝;采用本文的工程措施对混凝土进行保暖和养护,取得了良好的效果。

As we known,it is necessary to control the temperature for concrete construction in winter.Combining with the project in Tongchuan Water Factory,the last temperature and maintaining time for concrete construction in winter are computed and studied,and some construction measures in winter are put forward.The analysis results show that no crack appears after building up of the project,it is feasible to adopt the construction measures as mentioned above for maintaining of concrete.
