• Abstract:
  The Connecticut Department of Transportation (ConnDOT) currently permits the
  
  use of self-consolidating concrete (SCC) technology on a limited basis for
  
  precast drainage structures, barriers and retaining walls. These include but
  
  are not limited to catch basins, manholes, culverts, retaining walls, and
  
  barrier curbs. At this time, ConnDOT does not permit the use of SCC for
  
  prestressed concrete applications, such as for bulb-tee girders, box beams and
  
  deck slabs; and does not permit its use for cast-in-place applications.
  
  This study was conducted in order to help facilitate the specification of SCC
  
  technology by the ConnDOT. This included visiting precast plants that produce
  
  concrete products for ConnDOT and observing their practices, conducting a
  
  literature review on SCC, and summarizing a Research Advisory Committee survey
  
  conducted by the Missouri Department of Transportation appropriate to ConnDOT
  
  specifications. Based upon the findings of the study, it is recommended herein
  
  that ConnDOT’s SCC specification continue to be limited to precast concrete
  
  applications not involving any prestressed elements. Once ConnDOT implements a
  
  more rigorous SCC specification and acceptance process involving the use of
  
  more workability tests, ConnDOT should consider pilot projects for
  
  precast/prestressed bridge elements and cast-in-place concrete construction.
