  • 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.
