High-Strength Self-Consolidating Concrete (HS-SCC) and High-Volume Fly Ash Concrete (HVFAC) for Infrastructure Elements: Implementation

Because of its unique nature, high-strength self-consolidating concrete (HS-SCC) has the potential to significantly reduce costs associated with transportation-related infrastructure, benefiting both the Missouri Department of Transportation (MoDOT) and the residents of Missouri. HS-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. In addition to HS-SCC, innovative materials such as High Volume Flay Ash Concrete (HVFAC) also provides a significant potential to produce more cost effective mix designs for cast-in-place concrete. Since the 1930's, fly ash - a pozzolanic material - has been used as a partial replacement of portland cement in concrete to improve the material's strength and durability, while also limiting the amount of early heat generation. From an environmental perspective, replacing cement with fly ash reduces concrete's overall carbon footprint and diverts an industrial by-product from the solid waste stream (currently, about 40 percent of fly ash is reclaimed for beneficial reuse and 60 percent is disposed of in landfills). In this implementation study, a level of 50% fly ash to cement proportions will be utilized. This project aims to implement research undertaken at Missouri S&T and elsewhere on HS-SCC and HVFAC into an implementation project. It also aims to study the shear behavior in full-scale NU girders that are fabricated with HS-SCC.
