Abstract:
This presentation gives an overview of research performed on pumping pressure for high-strength SCC. A short-instrumented loop circuit was employed for pumping and concrete properties were evaluated during different pumping cycles. The influence of important mix design aspects, such as w/cm and paste volume, as well as pumping parameters flow rate and pipe diameter on pumping pressure is shown. On the other hand, the changes in SCC fresh properties due to pumping are also discussed.
