The use of self-consolidating concrete (SCC) for the manufacture of precast structural elements provides the benefits of increased rate of production, reduced labor needs (safety), and enhanced product quality. The same benefits apply to cast-in-place construction, especially with closely spaced reinforcing steel and narrow elements, which can cause problems with concrete consolidation.
The use of SCC in the United States has been limited because of concerns about certain design and construction issues. The South Dakota Department of Transportation (SDDOT) is interested in performing laboratory work to develop concrete mixture designs for SCC using crushed limestone (western South Dakota) and crushed quartzite (eastern South Dakota) coarse aggregate in the concrete. The concrete mixtures will be modified to allow for applications in precast and cast-in-place box culverts. The concrete properties, workability, ease of construction and performance would be monitored during construction of two precast and two cast-in-place box culverts. Using the developed SCC mixes.
