By optimizing the concrete materials and mixture ratio,prepared C100 ultra high performance concrete. The result show that the mechanical properties meet the requirements,also effectively solved the contradiction between the viscosity and the workability of C100 ultra high performance concrete. Loss of slump and slump flow has been effectively control,the working performance fully meet the requirements of site construction and pumping,the concrete has been vertical pumped to 411m in the height,created a new world re-cord for vertical pumping height.
