Concrete Innovation for Sustainable Building: A Comprehensive Study on Steel Fiber Reinforced Recycled Aggregate Mixes

Rahul Sharma, Harsh Rathore

Abstract


This study delves into Recycled Aggregate Concrete (RAC) as a sustainable alternative in construction, addressing environmental concerns linked to construction waste disposal. The research comprehensively examines RAC's compressive strength behavior, considering variations in recycled aggregate content and the introduction of steel fibers. Comparisons with conventional Natural Aggregate Concrete (NAC) assess RAC's practical viability. Results reveal a consistent decrease in compressive strength with higher recycled aggregate proportions. Testing 100 specimens with varying recycled aggregate and fiber dosage, the study indicates reduced compressive strengths in RAC compared to NAC, necessitating a thorough evaluation for structural applications. Introducing steel fibers proves effective in mitigating strength reduction. The research offers insights into RAC's compressive strength characteristics and its response to fiber reinforcement, contributing to the discourse on sustainable construction practices and understanding challenges and opportunities in incorporating recycled materials into concrete.
