HCSA膨胀剂在小瓦窑地下车库中的应用

The application of HCSA expansive agent in Xiaowayao garage

HCSA膨胀剂具有绝湿膨胀、膨胀能高和膨胀稳定等特点,本文介绍了HCSA膨胀剂在北京小瓦窑军队退休干部住房工程地下车库工程中的应用情况。通过合理设计限制膨胀率,优化补偿收缩混凝土配合比,加强混凝土生产控制,注重施工管理,加强混凝土振捣、养护和成品保护等工作,加快了施工进度,缩短工期,降低工程造价,并取得较好的抗裂防渗效果。

HCSA expansive agent has the advantage of moisture-free expansion, high expansion and good stability. The application of HCSA expansive agent for concrete in Beijig xiaowayao underground Garage raft was introduced in this paper. To make sure the project quality, the next measures were taken: design reasonable expansion ratio, optimize mix proportion of shrinkage compensating concrete, intensify concrete production control, construction management, enhance the movement of vibrator, curing and protection. The above steps accelerate construction schedule, short time limit for a project. and get a good effect of crack resistance and anti-seepage.
