Impact of steel fiber content on mechanical properties and EMI shielding of concrete structures

Key Points

• Increased steel fiber content significantly enhances mechanical properties and electro-magnetic interference (EMI) shielding in concrete structures.
• Specifically, the flexural strength increased by 25% with optimal steel fiber incorporation, indicating a strong structural performance improvement.
• Laboratory tests showed increased compression strength and durability, further supporting the benefits of steel fiber additions in construction materials.
• These findings highlight the potential for incorporating steel fiber in concrete, but field applications require further evaluation for real-world effectiveness.
