| Abstract: | The experimental studies on self-compacting and tiny expanding concrete filled in steel tube are introduced,which including the measurement of low ability of mixtures,the proportioning of the concrete filled in steel tube.The self-compacting and tiny expanding steel tube concrete has been applied in a large span bridge structure.The state of construction shows that the concrete have a good pump ability,a small loss of slump,a high strength early strength and a better self-compacting property. |
