摘要
介绍了钢管拱桥的微膨胀自密实泵送混凝土配合比设计过程,阐述了钢管混凝土工作原理和混凝土坍落度的确定等,并就此种混凝土的配合比设计提出了一些经验和方法,为类似工程的施工提供了一定的借鉴经验。
The process of mix proportion design in steel tube concrete arch bridge is introduced. Some experience and methods of the mix proportion design of micro expansive and self dense of C50 pump concrete is bring forward, which can be use for reference for similarity engineering.
