Abstract:
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 14 500 m3. 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.
