Fiber-Reinforced Concrete—From Fresh Properties to Structural Design: New Tools, Guides, and Reports-Recent Advances in Durability An Overview of the Document ACI 544.5R-10 and Updates (Recorded Presentation)

Recent Advances in Durability An Overview of the Document ACI 544.5R-10 and Updates (Recorded Presentation)

Video Transcription

Video Summary

The presentation discussed updates on the ACI 5445R document, focusing on fiber-reinforced concrete (FRC) and its durability. Key areas include the physical properties of fibers, their impact on reducing permeability and shrinkage, and the use of various fibers to improve the cracking and mechanical performance of concrete. The document, initially developed in 2010, is currently under revision, incorporating new research on topics like creep, shrinkage, and permeability. It highlights the benefits of blending fibers to enhance the performance of FRC, especially in tough environments. The presentation also covered FRC’s applications in industrial and structural contexts and discussed the potential corrosion of steel fibers, suggesting zinc-coated or stainless options for corrosive environments. Future updates will include information on nanofibers, crack healing, and sensing capabilities in fibers.
