补偿收缩混凝土在天津荣翠园地下室中的应用

Application of Shrinkage-compensating Concrete in Tianjin Rong Cui Yuan Basement

本文介绍了补偿收缩混凝土在天津荣翠园住宅楼地下室工程中的应用。采用HCSA高性能混凝土膨胀剂,通过优化混凝土配合比,加强振捣、养护,注重穿墙螺栓孔、水平施工缝、穿墙管等防水节点处理,地下室不渗不漏,取得较好的防水效果,同时降低工程防水造价。

The application of shrinkage compensating concrete was introduced in this paper. HCSA high performance expensive agent was used to make shrinkage compensating concrete. Concrete mix was optimized. Great attention was also paid to vibration, curing, and node waterproof treatment such as wall bolt hole, horizontal construction joint, and wall tube. Good waterproof effect and low cost were got as well.
