补偿收缩混凝土在超长地库筏板中的应用

Application of shrinkage compensating concrete in super-long raft foundations construction

本文介绍了补偿收缩混凝土在基础筏板施工中的应用。采用补偿收缩混凝土技术,取消后浇带,设置膨胀加强带,提高结构抗裂防渗能力,实现地下车库基础筏板混凝土结构自防水和超长结构连续施工。

The application of shrinkage compensating concrete in raft foundations construction is introduced in this paper. Expansion reinforcing band successfully substitute for post-pouting joint by using shrinkage compensating concrete. Crack resistance and antiseepage of structure was improved. Finally, concrete structure self-waterproofi ng and super-length structure seamless construction of underground garage come true.
