Abstract: Lots of skyscrapers are or will be built in China. High strength self-consolidating concrete is mainly used to construct composite steel concrete pillars and shear walls of core tube. It is introduced how to prepare high strength self-consolidating concrete with local raw materials and the controlling index for the workability of fresh concrete pumped to different heights. The pumpability of fresh concrete was evaluated in laboratory and in-site using normal workability evaluating methods and Sliper, a newly developed instrument to estimate pumpability of fresh concrete. A simulating pumping process of high strength self-consolidating concrete was done to investigate its performance using an experimental pumpline circuit with the total length of 2300m. C100 concrete was pumped one time to the height more than 1000m and cast without vibration in Shenzhen, China. Super-highly pumping of C70 self-consolidating concrete is widely performed now in the construction projects of skyscraper in China. Keywords: high strength self-consolidation
