摘　　要：以某高寒地区混凝土冬期施工为例,通过前期理论计算,分析了商品混凝土在严寒天气下从拌制、运输到现场浇筑时入模温度,并根据混凝土施工及养护温度的需要,确定了保温棚尺寸、热源能量及加热保温器具数量和点位配置方式,解决了传统施工方法能源浪费严重、暖棚内温度变化大、养护条件不达标等问题。Taking the concrete winter construction in a cold area as an example, through the early theoretical calculation, control of commercial concrete in the cold weather from mixing, transportation to the scene pouring into the mold temperature. According to the concrete construction and maintenance of the needs of the temperature, determine the size of the insulation shed, heat source and heating the number of insulation devices and point configuration. To solve the traditional construction methods of serious waste of energy, greenhouse temperature changes, maintenance conditions are not up to the construction process and other issues.
