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.
