1 Self-Consolidating Concrete for Cast-in-Place Bridge Components Research Significance Self-consolidating concrete (SCC) is a specially proportioned hydraulic cement concrete that enables fresh concrete to flow easily into the forms and around steel reinforcement without segregation and without any mechanical consolidation.

4• Drying shrinkage of SCC was significantly higher than predicted by AASHTO LRFD for CVC. The type of SCM had a significant effect on drying shrinkage (e.g., SCC containing Class C fly ash or GGBFS exhibited higher drying shrinkage than SCC containing Class F fly ash)
