• Abstract:
  Because of its unique nature, self-consolidating concrete (SCC) has the potential to significantly reduce costs associated with ; transportation-related infrastructure, benefiting both MoDOT and the residents of Missouri. SCC is a highly flowable, nonsegregating ; concrete that can be placed without any mechanical consolidation, and thus has the following advantages over conventional concrete: ; •decreased labor and equipment costs during concrete placement, ; •decreased potential for and costs to repair honeycombing and voids, ; •increased production rates of precast and cast-in-place elements, and ; •improved finish and appearance of cast and free concrete surfaces. ; However, concerns exist over the structural implications of SCC in cast-in-place and precast elements. Specifically, higher paste ; contents, higher fines contents, and the use of smaller, rounded aggregates may significantly alter the creep, shrinkage, bond, and ; shear strength of SCC mixes as compared to traditional concrete mixes with the same compressive strength. These concerns increase ; for mixtures that use untested aggregate types and various supplementary cementitious materials. Consequently, to achieve the ; benefits and potential savings with SCC, guidelines are needed for its proper application in bridges, roadways, culverts, retaining ; walls, and other transportation-related infrastructure components.
