摘要
张家口金垣置地广场(一期)工程基础底板及框架柱承台C40P8混凝土厚1450mm,总量1.45万m3,施工期该地区平均温度为负温。采用推移式分层浇筑、综合蓄热养护方法,根据热工计算结果确定养护参数,保证了大体积混凝土质量,达到预期目标。
In Zhangjiakou Jinyuan Land Plaza （Phase I） project, the foundation plate and frame column cap are made of C40P8 concrete, covering a total area of 14500m3. The average temperature in this region is below zero during the construction. Various measures, such as mobile pouring in layers and general heat accumulation curing method, etc., are adopted and curing parameters are determined according to the result of thermal calculation, to successfully guarantee the construction quality of massive concrete and reach the expected aims.
