城市轨道交通工程预拌混凝土质量控制

Quality Control of Premixed Concrete for Urban Rail Traffic Engineering

城市轨道交通工程预拌混凝土需求量大,质量要求高。文章基于南京宁和城际轨道交通工程实际,从原材料质量、配合比设计、混凝土生产过程以及施工质量等几个方面提出了城市轨道交通预拌混凝土质量控制的措施,可供类似工程混凝土施工参考。

The demand of premixed concrete in urban rail traffic engineering was large and required high quality. Based on the construction practice of Nanjing Ninghe intercity rail traffic engineering, the quality control methods of premixed concrete in urban rail traffic engineering were proposed from the aspects of material quality, concrete mix design, concrete production process and construction quality, which could be taken as reference for similar concrete construction.
