摘要
对12个应用泵送顶升法浇筑的自密实钢管混凝土结构进行了总结,并从顶升高度、配合比、自密实混凝土工作性能、力学性能等几个方面进行了分析。从自密实混凝土配合比优化入手实现混凝土泵送性能的提升,对解决实际工程问题具有一定的参考意义。
Twelve concrete-filled steel tube structures which are applied to pumping-up self-compacting concrete are summarized.It ’s analyzing from several aspects,such as lifting height,mix proportion,self-compacting working performance,mechanical property and so on.Also,the mix proportion of self-compacting concrete in order to promote the pumping performance of self-compacting was optimized , which has the certain reference significance in solving practical engineering problems.
