Tremie Concrete for Bridge Piers and Other Massive Underwater Placements

摘要

This study reviewed the placement of mass concrete under water using a tremie. Areas investigated included (1) Mixture design of tremie concrete including the use of pozzolanic replacement of portions of the cement; (2) Flow patterns and flow related characteristics of tremie-placed concrete; (3) Heat development and associated cracking problems for tremie concrete; (4) Prediction of temperatures in massive tremie concrete placements; and (5) Quality of tremie-placed concrete. Additionally, the tremie placement of a massive cofferdam seal for a pier of a major bridge and the tremie placement of a deep cutoff wall through an existing earthfill dam are examined.
