Self-compacting concrete-filled steel tube is different from ordinary self-compacting concrete in many aspects. According to the demands of on-site construction conditions and construction technology of continuous pumping lift-up method for the project of Huaxi No.1 steel tube arch bridge, property requirements of self-compacting concrete filled steel tube were proposed in this paper. By using the preparation techniques such as optimization of basic parameters of concrete mix proportion, admixture composition and mineral admixture addition, self-compacting concrete filled steel tube was prepared with the properties such as initial slump more than 24cm, initial slump flow above 650mm, T50 between 5s and 15s, no slump loss for 4h, no bleeding, strength grade above C60 and shrinkage-compensation etc. It was applied in the steel tube arch bridge project successfully using the construction technology of pumping lift-up method.
