This review evaluates natural and recycled fibres' impact on concrete's mechanical properties and durability, highlighting their eco benefits.
This review paper explores the use of natural and recycled fibres in concrete, focusing on their impact on mechanical properties and sustainability. Natural fibres, such as those from plants and animals, and recycled fibres, including synthetic and metallic varieties, are evaluated for their ability to enhance concrete’s compressive, tensile, and flexural strengths. The paper also examines durability factors like freeze-thaw resistance, chemical stability, and fire resistance. A comparative analysis highlights the benefits and limitations of both fibre types, emphasising their roles in reducing environmental impact and promoting sustainable construction practices. In addition, the review addresses the challenges of fibre-reinforced concrete, such as technical barriers and the need for standardised testing methods. Overall, the paper underscores the potential of natural and recycled fibres to improve concrete performance while contributing to more sustainable building materials.
