Fiber-Reinforced Self-Consolidating Concrete - Development and Use-Effect of Fiber Characteristics on Fresh and Hardened Properties of Fiber-Reinforced SCC (Recorded Presentation)

Effect of Fiber Characteristics on Fresh and Hardened Properties of Fiber-Reinforced SCC (Recorded Presentation)

Video Transcription

Video Summary

The presentation highlights the advances and applications of fiber-reinforced self-consolidating concrete (SCC), particularly focusing on repair applications. Initially developed at the University of Sherbrooke, the work primarily showcased the contributions of Fadil Qasimi. The City of Montreal has adopted SCC for many repair projects since 2003 due to its high durability and workability in challenging environments. The presentation discussed the efficacy of various fiber types—synthetic, hybrid, and steel—in enhancing the mechanical properties and durability of SCC, aiming at reducing cracking and improving structural integrity. The use of fibers, combined with expansive agents or shrinkage-reducing admixtures, was highlighted to offer excellent resistance to restrained shrinkage, ensuring longevity in infrastructure applications. The talk ended with an invitation to the Gordon Research Conference, emphasizing sustainable materials for infrastructure. Overall, the study underscores the importance of fiber-reinforced SCC in extending the service life and performance of concrete repairs.
