Comparative Study of Reinforced Concrete Using Human Hair and Aluminum Fibres

Abstract

This study investigates the efficacy of human hair and aluminum fibres as reinforcements in
concrete, analyzing their impact on compressive, flexural, and tensile strengths. Different fibre
percentages (0%, 0.5%, 1%, and 1.5% by weight of cement) are systematically incorporated into
concrete mixtures. Compressive strength tests on cubes, flexural strength assessments on beams,
and tensile strength evaluations on cylinders reveal insights into the material's load-bearing,
bending, and stretching capacities. Human hair-reinforced concrete showed significant
improvements in compressive strength. Results indicate a gradual strength increase in Human
Hair Fibre Reinforced Concrete (HHFRC) up to an optimal percentage. At the same time,
Aluminum Fibre Reinforced Concrete (AFRC) shows significant enhancement in higher fibre
content. AFRC's superior mechanical properties stem from aluminum fibres high tensile strength
and stiffness, enhancing bond formation and resulting in denser, stronger concrete. These findings
inform the selection of fibre reinforcement for concrete structures tailored to specific project
needs.
