Self-Compacting and Tiny Expanding Steel Tube Concrete Using in Large Span Bridges

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.
