Study on the flexural performance of 4D steel fiber-reinforced concrete under freeze-thaw cycles

Key Points

• Improved flexural performance directly correlates with the presence of steel fibers in the concrete mix.
• In tests, concrete reinforced with steel fibers showed better resistance during freeze-thaw cycles compared to standard concrete.
• Assessment using mechanical performance indicators confirmed significant benefits from steel fiber reinforcement.
• Findings highlight the importance of fiber-reinforced concrete designs for cold climate applications.
