Abstract：
Building height of Glory Xi'an Financial Center is 350m and no-stop concrete pumping technique was adopted. Considering that concrete strengthen, viscosity and pumping height are different in super-high building construction, C60 concrete was studied and concrete mixing proportion was designed according to different height nodes, to improve the pumpability of concrete. Various measures were adopted, such as calculation of concrete pumping pressure, reasonable arrangement of pump pipe, concrete pumpability control and high-pressure bleeding, etc., to save resources and guarantee engineering construction quality.
