Metrology Needs for Predicting Concrete Pumpability Related Information

Shirin Fataei – Technische Universität Dresden – Karlsruhe

The results indicate that the concrete pumpability, in terms of delivery rate for a given pressure, decreases by at least 30 % for 10 % increase in aggregates content by volume. The relative decrease in pumpability is more pronounced for CVC.

The second stage involved tremie placement of 9.2 m3 (12 yd3) of concrete to fill waffles and beams. The test confirmed that the high-performance, antiwashout concrete can flow across the panels without segregation. The test showed that the concrete did not need a protective mat under the wave and currents, due to its antiwashout characteristic.

The lubrication layer plays a governing role in predicting the pumpability of fresh concrete. To determine the effect of measurement methods on the characterization of the rheological properties of the lubrication layer, different measurement systems, including Sliper, tribometer, and the utilization of a mortar rheometer, were employed. The rheological properties and workability of bulk
