钢管混凝土的试制与工程应用

Trial-production of steel-tube concrete and its engineering application

从工程实际出发,介绍了钢管混凝土的试制及工程应用,分别阐述了混凝土配合比设计要点和具体施工工艺,通过试验确定主要材料与配合比,满足了大流动性、泵送施工要求,对今后同类工程具有一定指导作用。

To begin with the engineering practice,this paper introduces the trail-production of steel-tube concrete and engineering application,and respectively describes concrete mixing proportion design points and specific construction technology.Through experiments,it determines main materials and mixing proportion,and meets large-flow and pump construction requirements,which has played certain guiding significance for future similar engineering.
