浅谈混凝土工程冬季施工技术

Discussion on Construction Technology of Concrete in Winter

严格控制混凝土拌合时间和坍落度,降低配合比中的用水量,避免混凝土产生早期冻害,并尽量缩短运输时间和距离,加快浇筑速度,防止热量散失过多,采取相应的保温保湿措施,以保证混凝土强度。通过实例,分析了建筑工程混凝土受冻害损伤的主要原因,并据此分析了施工过程中应采取的抗冻施工措施。

In order to assure the strength of concrete, mixing time and slump should be controlled strictly,as well as decreasing water amount of mix proportion,avoiding early freezing injury,reducing transportation time and distance,increasing pouring speed,preventing more heat dissipating,and adopting corresponding insulation and moisture retention measures.Through actual engineering,the causes of freezing injury are analyzed,the same as anti-freezing construction methods.
