The effects of steel fiber content and thermal curing on the mechanical and durability properties of ultra-high performance concrete with iron tailings

Key Points

• Improved durability properties are associated with increased steel fiber content and thermal curing.
• Significant enhancements in compressive strength are observed at varying steel fiber ratios in concrete mixes.
• Experimental analysis across several variations highlights the roles of iron tailings and thermal curing in structural integrity.
• Results suggest that optimized steel fiber and curing methods may enable more resilient concrete applications.
