  • 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.
