A Review on Date Palm Fiber as a Sustainable Reinforcement for Concrete Applications

Date palm fiber-reinforced concrete (DPFRC) has appeared as a promising alternative in the construction industry, offering an eco-friendly and sustainable solution to improve the mechanical properties of concrete. This comprehensive review delves into the extensive research conducted on DPFRC, exploring its potential applications, mechanical characteristics, and environmental benefits. The rationale of this review is based on the comparative analysis of DPF-reinforced concrete with various other fiber-reinforced concretes in terms of carbon footprint, sustainability, mechanical properties, ductility, acid attack and thermal conductivity. Furthermore, the review examines the influence of fiber content, aspect ratio, and orientation on the tensile (TS), flexural (FS), and compressive strength (CS) of DPFRC. DPF is responsible for a small increase in CS and a remarkable increase in TS and FS in concrete. The optimum content of 0.1–1% and the small length of fibers (<50 mm) is found to be optimum for maintaining CS and water absorption, while the percentage up to 5% is found to be significant for improving TS and FS. Apart from the mechanical characteristics, the review investigates the durability aspects of DPFRC, including resistance to shrinkage, cracking, and corrosion. High ductility and thermal insulation properties also make it an ideal candidate for specific infrastructure applications. Moreover, the review comparatively analyzed the sustainability implications of DPFRC, emphasizing its potential to mitigate carbon emissions, reduce waste from agricultural residues, and contribute to the circular economy. Case studies and practical applications of DPFRC in construction projects are also examined, showcasing its feasibility and effectiveness in real-world scenarios. Overall, this review provides valuable insights into the untapped potential of DPFRC, serving as a comprehensive resource for researchers, engineers, and practitioners seeking to harness the benefits of this innovative construction material.
