Abstract:
This session intends to inform concrete producers, contractors, academics, and students on the latest developments, common practices, and problems associated with pumping of self-consolidating concrete (SCC). The session focuses on selecting materials and optimizing mixture design to ensure adequate pumping of SCC. Practical experiences on the quality control of SCC for the construction of the Burj Khalifa, as well as the influence of SCC fresh properties on changes in the air void system due to pumping are discussed. The latest theoretical developments on prediction of pumping pressure, influence of constituent elements, and the changes in fresh concrete properties are also presented.
