• Abstract:
  Signifi cant anomalies have been observed in many of the recently drilled shaft constructions
  
  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 diffi culties noted in some pilot studies. As
  
  an example, SCC was used in the drilled shafts for the Huey P. Long Bridge in New Orleans, La,
  
  and performed satisfactorily. However, when conventional concrete was used for the Audubon
  
  Bridge in Louisiana, problems were noted in the construction as well as the shaft resistance. Both
  
  projects consist of large size shafts constructed in the Mississippi River under similar conditions.
  
  One possible explanation for the diff erences in shaft performance is the concrete mixture design.
