The composite construction materials industry has been changing rapidly in order to meet all the requirements for bridge production. The bridge construction industry is now realizing the need for long-lasting materials. A bridge design needs to meet the public demands whether it is built using modern composites or traditional steel.
When it comes to exploring strong and economically viable construction materials, glass fiber reinforced polymer (GFRP) materials offer the solution. Composite materials have the potential to build maintenance-free and cost-effective bridge infrastructure. Low lifecycle costs, corrosion resistance, and high strength of GFRP-reinforced concrete members are some of the characteristics that make these materials unique and promising.
Various industries consider composite materials as designer materials, capable of being tailored to any need. Based on the requirements, the manufacturer can customize the constituents of GFRP reinforcement: fibers, resins, and the architecture of the composite, as well as the lay-up and fiber orientation.
Widespread application of GFRP
For the widespread application of GFRP composites in bridge infrastructure, it’s important to improve the viability of composites. For a successful widespread implementation of GFRP reinforcement and other materials, bridges reinforced with fiberglass must meet the following expectations:
- Economy
- Serviceability
- Safety
- Aesthetics
- Constructability
Safety
Safety is one of the prime responsibilities in relation to bridge construction. Catastrophic incidents such as bridge collapses and highway accidents are unacceptable. Billions of dollars are allocated every year to improve the safety of concrete infrastructure in North America and across the globe. Moreover, safety has been the subject of academic research focusing on exploring new possibilities to eliminate the element of risk.
Durability
It is important to recognize the importance of deterioration of concrete members in the long-term performance of the bridge. Concrete structures reinforced with steel can’t meet the durability criteria because of the inherent property of steel to corrode. The durability tests are largely focused on studying the potential exposures of the highway bridge environment. GFRP-reinforced bridges after being in practice for a considerable period of time have shown adequate durability.
Economy
Considering the low construction and rehabilitation funds, it’s critical to adopt economically viable solutions. However, other requirements can’t be undermined while dealing with the economy. It is excessively difficult for the construction industry to build durable structures with limited budgets.
The initial cost of composites might be higher than that of traditional materials. However, the growing price of steel will pave the way for the rapid growth of composites. Considering the lifecycle costs and promising properties, GFRP reinforcement will gain unprecedented popularity in the future.
Factors that can offset the high initial cost of GFRP rebar include lower lifecycle costs, ease of installation, and high tensile strength. Unique characteristics of GFRP rebar will help the construction industry build long-lasting structures in extremely corrosive environments.
