Self-Consolidating Concrete for Precast Structural Applications: Project Summary Report (0-5134-S)

Self-consolidating concrete (SCC) is a relatively new technology that has potential to lower construction cost, improve safety at work sites, and increase construction productivity. As with most new technologies, research is needed to determine pertinent characteristics such that safe, fast, reliable, repeatable, and durable products can be made with this material. This research will investigate both the early age (fresh and transitional) and later age (hardened) characteristics of SCC using materials available in Texas. Special attention will be focused on requirements for precast, prestressed concrete products and how SCC will impact the constructability and performance of these elements. From the testing and observations observed from the research, the researchers will develop a manual for the inspection of fresh SCC and will identify needed changes to specifications and design codes for the Texas Department of Transportation.
