Sustainable Innovative New Advanced Materials for Underground Infrastructure Projects

The utilization of Fiber-Reinforced Polymer (FRP) bars in underground infrastructure projects, such as tunnels, presents a sustainable and innovative solution to address the challenges posed by harsh environmental conditions. This paper discusses the properties of FRP materials, including their corrosion resistance, lightweight nature, and mechanical strength, which make them ideal for applications in tunnel construction. The study highlights the benefits of using FRP as reinforcement, including reduced maintenance costs and enhanced durability over traditional steel reinforcements. Additionally, it explores the acceptance and application of FRP within the construction industry, emphasizing the need for updated guidelines and standards to facilitate wider adoption. Through a review of existing literature and practical applications, this research provides insights into the advantages of incorporating FRP in tunnel structures, paving the way for future studies and advancements in the field.
