Field Experience and Structural Performance of Self-Consolidating Concrete in High-Rise and Bridge Construction-Shear and Bond Strength of Self-Consolidating Concrete for Cast-in-Place Bridge Applications (Recorded presentation)

Shear and Bond Strength of Self-Consolidating Concrete for Cast-in-Place Bridge Applications (Recorded presentation)

Video Transcription

Video Summary

Professor George Marcuse presented on the structural performance of self-consolidated concrete (SCCC) girders, focusing on shear and bond strength, particularly for bridge construction. He noted the lack of design specifications for SCCC in bridge applications and the need to integrate it into AASHTO guidelines. The research, part of NCHRP Project 1816, aimed to evaluate the fresh and hardened properties of SCCC and compare them with traditional concrete (CVC). Key findings showed no significant difference in shear strength between SCCC and CVC, though variations exist in bond strength, suggesting a modification factor for development length with SCCC. The study highlighted the importance of considering various factors in bond strength, emphasizing the overall potential and considerations for SCCC in construction. Professor Marcuse concluded by addressing concerns on SCCC's lower bond, explaining that SCCC exhibits consistent and sometimes superior performance under specific conditions.
