在严寒地区,因混凝土的表面系数大,依靠混凝土自身的水化热远不能满足养护所需的热量和温度,为满足混凝土养护条件及早期强度要求,传统采用表面保温、外部加热方法,热量损失大,热效率低,浪费严重。为此,根据实际工作经验,阐述了一种在严寒地区施工的技术,希望可为同行业人士在类似工程中提供参考借鉴。
In the cold area, because of the large surface coefficient of concrete, relying on the concrete hydration heat far can not meet the required maintenance of heat and temperature, in order to meet the concrete curing conditions and early strength requirements, the traditional use of surface insulation, external heating methods, heat loss Large, low thermal efficiency, serious waste. To this end, according to the actual work experience, elaborated a technology in the cold areas of construction, hoping for the same industry to provide reference for similar projects.
