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。 This paper introduces the application of compensating shrinkage concrete in the basement construction of Rongrui Garden residential building in Tianjin. Using HCSA high performance concrete expanders, through optimizing the mix proportion of concrete, strengthening the vibrating and curing, paying attention to the bolt holes in the wall, the horizontal construction joints and the wall pipe and other waterproof joints, the basement does not seep and leaks, so as to obtain better waterproofing effect , While reducing the project waterproofing costs.
