摘　　要：普通混凝土掺入膨胀剂配制成的补偿收缩混凝土常用于混凝土结构自防水、大体积混凝土、超长混凝土结构等,是减少混凝土结构裂缝的主要措施之一。南水北调某配套工程混凝土底板采用补偿收缩混凝土并设连续式膨胀加强带,以避免或减少混凝土因干燥收缩和温度收缩而产生的裂缝,论述了水利工程中补偿收缩混凝土应用的施工技术及注意事项。Concrete mixing expansive agent shrinkage compensating concrete prepared, used for self waterproofing of concrete structure, concrete, overlong concrete structure, is one of the main measures to reduce cracks in concrete structures.Water diversion concrete slab in a supporting engineering design and adopted shrinkage compensating concrete continuous expansion strengthening belt, to avoid or reduce the cracks of concrete because of dry shrinkage and temperature shrinkage, this paper discusses the water conservancy project construction technology of shrinkage compensating concrete application and matters needing attention.

关 键 词：补偿收缩混凝土 大体积混凝土 底板
