Self-Consolidating Concrete for Infrastructure Elements

Because of its unique nature, self-consolidating concrete (SCC) has the potential to significantly reduce costs associated with transportation-related infrastructure, benefiting both Missouri Department of Transportation (MoDOT) and the residents of Missouri. SCC is a highly flowable, non-segregating concrete that can be placed without any mechanical consolidation, and thus has the following advantages over conventional concrete: (1) decreased labor and equipment costs during concrete placement, (2) decreased potential for and costs to repair honeycombing and voids, (3) increased production rates of precast and cast-in-place elements, and (4) 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.
