西北地区超长桩基混凝土配合比设计研究

Study on the design of mix proportion super-long pile concrete in northwest China

简述了超长桩基混凝土及配合比设计思路,依托西安迈科商业中心超高层建筑项目,结合西北地区气候特征及本地原材料,以C45强度等级桩基混凝土设计为例,通过对混凝土工作性能、凝结时间等调节,顺利完成了超长桩基混凝土的配制试验。

The thought in the super-long pile concrete mix proportion which would be used in super-high floors located in Xi＇an Mike Commercial Center was described briefly.Combined the climatic Characteristics and rural materials of the northwest, the example of the designed in C45 strength grade of concrete and adjusting of the performance and setting time of concrete ,the pouring of the super-long pile concrete was finally succeed.
