THE INVESTIGATION AND APPLICATION OF SELF-COMPACTING EXPENSIVE CONCRETE FILLED STEEL TUBE

摘要：

We prepared the self-compacting expensive C50 concrete that possesses good workability,high strength,high early strength and expansive properties.The self-strains of steel tube caused by the core concrete expansion and the maximum bearing capacity of the self-compacting expensive concrete filled steel tube were studied,and the results show that the core concrete is under three-dimensionally suppressed,and the bearing capacity is 7％ more than that of ordinary concrete filled steel tube.The achievements in this paper have been applied in the real steel tube arch bridges,and the engineering effect is good.
