本文介绍了补偿收缩混凝土超长结构连续施工技术在地下室工程中的应用,选用限制膨胀≥0.08%的高性能混凝土膨胀剂配制补偿收缩混凝土,依据结构特点优化设置膨胀加强带,利用连续式、后浇式膨胀加强带替代后浇带,加快施工进度,节省费用。
In this paper, the application of continuous construction technology of compensating shrinkage concrete over long structure in basement construction is introduced. High performance concrete expansive agent with limiting expansion ≥0.08% is used to prepare compensatory shrinkage concrete. Expansion reinforcing belt is optimized according to structural characteristics. Continuous, Pouring expansion tape to replace the pouring zone to speed up the construction progress, save costs.
