Self-Consolidating Concrete: A Synthesis of Research Findings and Best Practices

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.
