    Abstract：The high strength self-compacting concrete in tower barrel of wind power was prepared through mix proportion design and optimization with qualified self compactness and compressive strength that meet the design requirement. Field application indicates shows that the high strength self-compacting concrete has a good pump ability that can easy to be jacked up slowly，and the tower barrel show a good appearance quality.
