Fiber-Reinforced Concrete for Optimized and Sustainable Construction
Wednesday, October 20, 2021 1:00 PM - 3:00 PM
The application of fiber-reinforced concrete (FRC) has significantly expanded in the last several years along with the publication of various guides and reports by ACI Committee 544. In this session, actual projects will be presented in which fiber reinforcement has fully or partially replaced reinforcing bars in concrete, allowing optimization of construction time and procedures. Presentations will include basics of design for FRC and construction practices. Examples are industrial slabs-on-ground, light rail track slabs, foundation walls, tunnel segments, environmental structures. This session be will useful for students, engineers, contractors, testing labs, and government officials.
(1) Review some basics on the design and construction of fiber-reinforced concrete;
(2) Discuss some of the existing / ongoing projects with fibers reinforcement;
(3) Demonstrate how fibers can be used to optimize the construction process;
(4) Summarize the positive impact of FRC in reducing carbon footprint of construction.
This session has been approved by AIA and ICC for 2 PDHs (0.2 CEUs). Please note: You must attend the live session for the entire duration to receive credit. On-demand sessions do not qualify for PDH/CEU credit.
Fiber-Reinforced Concrete for Optimized Construction of Light Rail Track Slabs
Presented By: Barzin Mobasher
Affiliation: Arizona State University
Description: This presentation will cover the application of steel fibers in track slabs for a city project including design, small scale and full-scale testing and optimization of construction with respect to time, labor and environment.
Owner’s Perspective for Use of Fibers in Industrial Floor Slabs
Presented By: Jason Harris
Affiliation: General Motors
Description: This presentation will cover the modern use of steel and synthetic macro fibers as the reinforcement for industrial concrete slabs in GM manufacturing facilities from owner's perspective.
Innovative SFRC Floors: Research, Design Principle, and Applications
Presented By: Hendrik Thooft
Description: This presentation will discuss the applications of SFRC beyond slabs on ground. It will cover the design and construction aspects of steel fibers for slabs on pile and elevated slabs, from research to application and sustainability.
Design and Application of Fiber-Reinforced Precast Concrete Segmental Lining
Presented By: Mehdi Bakhshi
Description: This presentation reviews the design aspects of FRC precast tunnel segments for lining application and shows actual projects where fibers were successfully used for optimized construction.
Design and Construction of Residential Concrete Walls with Fiber Reinforcement
Presented By: Amir Bonakdar
Affiliation: Euclid Chemical
Description: This presentation will cover an optimization of design and construction process using synthetic and steel fibers for wall applications including foundation walls and ICF walls. Design, construction, economics, and carbon footprint of FRC walls will be discussed.
Design and Application of FRC Elevated Slabs
Presented By: Giovanni Plizzari
Affiliation: University of Brescia
Description: This presentation reviews the design and modeling steps for using fiber reinforced concrete, specific to elevated slabs. Serviceability and ultimate state designs will be discussed using experimental and numerical methods.
