谈自密实混凝土施工技术

摘要

以北京市南水北调工程水工隧洞现浇自密实混凝土工程为例,对自密实混凝土配合比设计、原材料选择和工程应用施工操作要点等加以说明和介绍,以期促进自密实混凝土施工技术的推广应用。%Taking the cast-in-place self-compacting concrete project in South-North Water transfer project in Beijing as the background,the paper indicates and introduces the proportional ratio,the selection of raw materials,and the operation points for the engineering application for the self-compacting concrete,so as to enhance the extensive application for the self-compacting concrete construction.
