自密实混凝土在钢管混凝土结构中的应用

摘要

本文结合工程实例,根据工程实际应用经验,提出对高抛自密实混凝土的工作机理、配合比设计、工作性评价方法、试验方法,介绍自密实混凝土在钢管混凝土结构中的应用。%Combined with the project examples,this article puts forward the working mechanism,mixture design,workability evaluation method and test methods of highly-casting self-compacting concrete according to actual engineering application experiences,then introduces the application of self-compacting concrete in steel-tube-concrete structure.
