Polyvinylpyrrolidone -modified steel fibers for enhancing interfacial bonding and flexural properties of ultra-high performance concrete

Key Points

• Enhanced interfacial bonding significantly improves flexural properties of ultra-high performance concrete.
• Measurements reveal a marked increase in flexural strength by approximately 25% with modified fibers.
• Experimental analysis focused on the interaction between polyvinylpyrrolidone-modified steel fibers and concrete mix design.
• Finding supports the use of polymer-modified fibers for stronger, more durable concrete applications.
