国内外对混凝土冬季施工理论和方法的分析研究认为,当外界气温降到4℃时,只要采用适当的施工方法,避免新浇筑混凝土早期浸冻,使外露混凝土与冬季气温保持较小温差,就会取得较好的施工效果。本文通过对冬季施工混凝土浸冻机理的分析,提出几点有效防止混凝土冻融破坏的措施,以达到延长工程使用寿命的目的。 Domestic and international analysis of the theory and method of concrete construction in winter that when the outside temperature dropped to 4 ℃, as long as the use of appropriate construction methods to avoid the early pouring of fresh concrete pouring, the exposed concrete and winter temperatures to maintain a small temperature difference Will achieve better construction results. In this paper, through the analysis of the mechanism of winter construction of concrete soaking, put forward some measures to effectively prevent the concrete freeze-thaw damage in order to achieve the purpose of extending the service life of the project.
