• Abstract:
  Significant anomalies have been observed in many of the recent drilled shaft construction projects throughout Louisiana. ; The anomalies typically occur in the form of honeycombing within the zones of heavy reinforcement or sometimes at the ; shaft bottom. Self-Consolidating Concrete (SCC) has shown great potential to overcome the difficulties as noted in some ; pilot studies. For example, SCC was used in the drilled shafts for the Huey P. Long Bridge in New Orleans and performed ; satisfactorily. In contrast to the Huey P. Long Bridge, conventional concrete was used for the Audubon Bridge. Problems ; were noted in the construction as well as the shaft resistance. Both projects consist of large size shafts constructed in the ; Mississippi River in similar conditions. ; This project was undertaken to determine the use of SCC and various test methods to assess the suitability of SCC in ; underwater placement conditions.
