Abstract: The contradiction between C60 high-performance concrete's viscosity and pumpability was always a major problem in high pumping concrete construction.Taking a high-rise building concrete pumping construction of a tall building for example,it was firstly selected the C60 high-performance concrete proportion of mixture suitable for high pumping,and also verified the critical parameters of the pumping equipment from the theoretical calculations and actual estimates,it was selected the HBT90CH-2135D pumping equipment of Sanyi Heavy Industry,eventually the concrete pumping scheme of two-pump and two-tube to the top layer was used,and it was successfully overcome the contradiction between C60 high-performance concrete's viscosity and pumpability,thus pumping C60 high performance concrete to a height of 383 m smoothly,which had important reference and practical significance to high performance concrete pumping construction for superhigh buildings.
