Concrete infrastructure holds immense importance when it comes to the economic growth of a region. Civil structures must be designed and built with satisfactory materials and techniques so that they can be maintained in good condition for a longer useful life without the need for rehabilitation. Durable infrastructure systems, such as bridges, roads, water systems, and buildings, play a vital role in building a healthy economy. Therefore, the need for cost-effective and corrosion-free building materials has reached an unprecedented level.
Fiber Reinforced Polymers (FRP), also known as composites, have been used for so many years in various sensitive applications where the harsh environment is a major concern for structural engineers. The excellent results produced by FRP materials in civil infrastructure have resulted in a shift from traditional reinforcement to FRP in most developed countries. The ability to withstand harsh environments and protect reinforced concrete against corrosive agents is what makes fiberglass rebar and other GFRP building products such an amazing alternative to conventional concrete reinforcement techniques.
The construction industry relies heavily on design codes, standards, and specifications so that materials can be used accordingly. In the past, FRP products were designed, manufactured, and manufactured using general codes and design manuals provided by the proper authorities. Extensive academic and on-site research has resulted in the development of in-depth and specific FRP design codes and specifications, making it easier for the construction industry to embrace advanced composite materials as a permanent alternative to substandard and conventional materials. .
“Pre-Standard for Load and Resistance Factor Design (LRFD) of Pultruded Fiber Reinforced Polymer (FRP) Structures” is a new design code developed by the American Society of Civil Engineers (ASCE) and the American Association of Compound Manufacturers (ACMA). The development of these new codes would help structural engineers build durable and safe projects. Furthermore, the presence of design codes would pave the way for FRP composite materials to dominate the market.
Fiberglass rebar is probably the most important FRP product that is widely used for concrete reinforcement. Rock bolts, lifting anchors, tendons and form ties are some of the GFRP construction products. The development and distinctive properties of composite building products have received a warm response from the civil engineering community. With the advent of new design codes and specifications, civil engineers have shown confidence in GFRP building products.
A civil engineer must be well acquainted with the qualitative and quantitative properties of construction materials that are used in the construction of concrete structures. Design codes, manuals, and specifications really help engineers understand a material’s strength and applications.
