TRB's National Cooperative Highway Research Program (NCHRP) Report 628: Self-Consolidating Concrete for Precast, Prestressed Concrete Bridge Elements explores recommended guidelines for the use of self-consolidating concrete (SCC) in precast, prestressed concrete bridge elements. The report examines the selection of constituent materials, proportioning of concrete mixtures, testing methods, fresh and hardened concrete properties, production and quality control issues, and other aspects of SCC.
Attachment D, "Research Description and Findings," provides detailed information on the experimental program and data analysis, and the findings of the literature review.
