In order to solve the world-class technical problem of ultra-high strength concrete development and pumping, a Chinese company completed the 380m ultra-high pumping test of C130 ultra-high performance steel fiber manufactured sand concrete in Building 1 of Guiyang center project, a key project in Guizhou Province, on December 6. It created a world record of the pumping height in a real project which use full manufactured sand.

C130 ultra-high strength concrete greatly reduces the area of concrete components and increases the building use area, which is in line with the concept of improving land utilization rate of super high-rise buildings, and can effectively save concrete and formwork and reduce labor.
