摘要
研究了混凝土结构在冬季施工中的方法。在-15℃以上的气温环境中,采用42.5以上等级的硅酸盐水泥或普通硅酸盐水泥,用全封闭式搅拌站进行搅拌,采取延长搅拌时间、保温养护等一系列升温措施,确保成型后温度不低于5℃,达到理想的效果。
The winter construction method of concrete structure is studied, which is in the environment above -15℃ ,using portland cement above rank 42.5 or the ordinary portland cement,stirring with the total-closed agitating station,taking measures of lengthening the stirring time and preserving heat to ensure the temperature not to be lower than 5℃after shaping and achieve the ideal effect.
