Abstract: Conventional concrete tends to present a problem with regard to adequate consolidation in thin sections or areas of congested reinforcement, which leads to a large volume of entrapped air voids and compromises the strength and durability of the concrete. Using self-consolidating concrete (SCC) can minimize the problem since it was designed to consolidate under its own mass. This study examined several mixture designs in the laboratory with the goal of creating mixtures with desirable flow characteristics that did not require additional consolidation yet provided adequate compressive strength, low permeability, shrinkage control, and resistance to cycles of freezing and thawing. The results provided a foundation for determining if SCC could be produced on a commercial scale using locally available materials at two concrete plants. SCC from one plant was used in a field application for a small bridge in a residential area. The results showed that with adjustments to the mixture proportions, SCC can be produced successfully and provide many benefits to transportation agencies and the construction industry.
