Structural Applications for Self-Consolidating Concrete

The South Dakota Department of Transportation (SDDOT) recently submitted a successful application for funding from the Federal Highway Administration's Innovative Bridge Research and Construction Program (IBRC). The application proposed laboratory evaluation of Self Consolidating Concrete (SCC) mixture designs for use in precast and cast-in-place box culverts and other structural applications. SCC is a specially proportioned hydraulic cement concrete that flows easily into forms and around reinforcement without segregation. Use of this type of concrete for the manufacture of precast elements provides the benefits of increased rate of production, safety and reduced labor needs. These same benefits apply to cast-in-place construction, especially with closely spaced reinforcing steel, which can cause problems with concrete consolidation. In spite of its benefits and widespread use in Japan and Europe, the use of SCC in the United States has been limited because of concerns about certain design and construction issues that are perceived to influence the structural integrity of the structural element. These issues include workability, strength development, creep and shrinkage properties, durability, and other factors that influence constructability and performance. SDDOT needs to determine SCC mix designs with materials that are specific to South Dakota. There is also a need to determine if there are potential constructability and production issues. If it is determined that SCC can be used with no detrimental effects or production issues, then recommendations for its use need to be developed. Research is needed to verify that the use of SCC is advisable in these applications and does not create performance issues with respect to durability, surface finish, placement, scaling, or functional requirements of hardened concrete.The objectives of this research project are to: (1) Evaluate the feasibility and performance of SCC for use in cast-in-place and precast concrete products; and (2) Develop draft specifications, acceptance criteria, mix qualifications, and guidelines for use of SCC by SDDOT.
