NCHRP: Self-Consolidating Concrete

Self-Consolidating Concrete
Client: National Cooperative Highway Research Program (NCHRP)
Audience: NCHRP managers and staff; state DOT research staff

This NCHRP’s Ready Results publication explores how NCHRP Report 819: Self-Consolidating Concrete for Cast-in-Place Bridge Components developed guidelines for using self-consolidating concrete (SCC) in cast-in-place bridge components and proposed changes to the American Association of State Highway and Transportation Officials’ (AASHTO’s) specifications to encourage appropriate use of the material by state transportation departments. Many states only permit use of materials that are included in AASHTO specifications, or they require independent testing of SCC materials. With the new specifications, agencies will have clear guidance and appropriate test methods for the use of SCC.
