Although the strength of glass fiber-reinforced polymer (GFRP) was realized more than five decades ago, growth constraints such as limited practical data, high initial cost, and lack of design guidelines continued to limit their scope and applications as a long-lasting construction material. The civil engineering community, however, adopted advanced composite materials such as fiberglass rebar to resolve some of the longstanding structural problems such as corrosion of steel reinforcement, rapid concrete deterioration, and costly maintenance. Fiberglass manufacturers can now produce premium quality rebar following the development in manufacturing techniques.
It is useful to study various aspects of GFRP composites, including their mechanical properties and structural characteristics so that their applications in civil engineering can be clearly defined. Despite the constraints, GFRP rebar and other products are already being used as rust free, lightweight and high strength concrete reinforcement. The electromagnetic neutrality of GFRP materials makes them ideal for sensitive structural applications such as research laboratories, MRI units and educational institutes.
It is critical to ensure sustainability and environmental stability while selecting construction materials for various applications. There are a number of research papers and case studies which explored the viability of composites in building futuristic concrete infrastructure. According to most of the studies, the benefits of using GFRP composites, as compared with traditional materials, include extended lifespan without expensive maintenance. In addition, composite materials are advantageous in terms of environment. The overall compositions of GFRP fiberglass rebar can be customized depending on the unique requirements of a project.
The seismic retrofitting and rehabilitation of structurally deficient concrete structures using glass fiber-reinforced polymers are well-known techniques. The strength of externally bonded GFRP composites has demonstrated many advantages including the ease of installation and strength-to-weight ratio. The ease of installation and transportation without using heavy machines makes these materials economically viable for many waterside concrete applications.
The production methods for the production of GFRP composites have been revolutionized by sophisticated manufacturing techniques. These methods have enabled manufacturers to produce superior quality laminates with accurate fiber alignment and minimal voids.
Since the Industrial Revolution, the construction industry has been experiencing a lack of sustainable construction products. Before the introduction of composites, the construction industry was considered as labor intensive and technologically backward as compared with other industries. However, things have changed dramatically over the last three decades. Advanced materials and construction practices have played a key role in transforming the construction industry into a technology-driven industry. If you are looking for innovative concrete reinforcement for your next construction project, it’s important to consider GFRP technology which is designed to serve the future.
