Through the optimization of concrete mix proportion,the influence of sand ratio and super absorbent polymer on the worka-bility of self-compacting concrete has been studied.Meanwhile deals with the pumping property and slump-retaining ability of self com-pacting concrete through optimizing pumping agent formulation.And the C60 self-compacting concrete-filled steel tubes applied to lifting up construction has been formulated and put to use in the Chengdu Huazhi Plaza project successfully.
