| 摘 要： | 自密实混凝土在近代建筑结构和桥梁结构中有了较大的发展，特别在密集配筋、空间狭窄、不易振捣的钢筋混凝土结构中广泛应用。但在实体项目的运用中需要对配合比进行充分的试配验证。南京青奥公园步行桥（“南京眼”）在结构复杂的塔柱T0节段的浇筑中采用了C50自密实混凝土，主要介绍自密实混凝土试配过程及质量控制要点，以便推动其广泛应用。

| Abstract: | There is great development of self-compacting concrete in modern building structure and bridge structure. It is widely used in reinforced concrete structure with dense reinforcement, narrow space and which is hard to vibrate. It need mix proportion test verification in projects. C50 self-compacting con？crete is used in T0 section of Nanjing Youth Olympic Park（Nanjing Eye）. This article introduces the test-mixing procedures and the quality control points of self-compacting concrete, so as to promote its wide ap？plication. |
