Self-Consolidating Concrete for Cast-in-Place Bridge Components

TRB's National Cooperative Highway Research Program (NCHRP) Report 819: Self-Consolidating Concrete for Cast-in-Place Bridge Components presents recommended guidelines for the use of self-consolidating concrete (SCC) in cast-in-place highway bridge components. These guidelines address 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.

The report also presents proposed changes to the AASHTO LRFD Bridge Design and Construction Specifications to address use of SCC for cast-in-place highway bridge components. The information contained in the report will guide materials and bridge engineers in evaluating, selecting, and specifying SCC mixtures for use in cast-in-place concrete bridge components, thereby facilitating construction, improving the working environment and safety, and reducing cost.

Six appendices from the research agency’s final report provide detailed information on the experimental program outlined in NCHRP Report 819 .
