This study explores the mechanical performance and durability of M35 grade Hybrid Fiber Reinforced Self-Compacting Concrete (HFRSCC) incorporating varying proportions of hybrid steel fibers. Experimental investigations assess workability, compressive strength, flexural strength, impact resistance at normal temperatures, and residual strength at elevated temperatures. Results indicate that HFRSCC exhibits a significant increase in compressive strength (37.26%), flexural strength (166.5%), and impact strength (300.33%). These findings highlight HFRSCC’s potential for application in high-performance concrete structures, offering improved longevity and reduced maintenance requirements.

摘要

This study explores the mechanical performance and durability of M35 grade Hybrid Fiber Reinforced Self-Compacting Concrete (HFRSCC) incorporating varying proportions of hybrid steel fibers. Experimental investigations assess workability, compressive strength, flexural strength, impact resistance at normal temperatures, and residual strength at elevated temperatures. Results indicate that HFRSCC exhibits a significant increase in compressive strength (37.26%), flexural strength (166.5%), and impact strength (300.33%). These findings highlight HFRSCC’s potential for application in high-performance concrete structures, offering improved longevity and reduced maintenance requirements.
