![]() The bars are non-metallic, so they are not susceptible to electrochemical corrosion that may result from chloride exposure in coastal areas or where chloride deicing salts are used. The standard is modelled after ACI CODE 318 Building Code Requirements for Structural Concrete and currently limited to the design and construction of cast-in-place reinforced concretes with GFRP reinforcing bars meeting ASTM D7957 Standard Specification for Solid Round Glass Fiber Reinforced Polymer Bars for Concrete Reinforcement shown in Figure 1.įigure 1 Placement of GFRP Reinforcement Benefits and Uses of GFRPĬompared to steel reinforcing bars, the lighter weight of GRFP reinforcing bars are easier to install and may reduce the overall structure’s weight. GFRP Reinforced ConcreteĪCI Committee 440 developed CODE 440.11 to establish minimum requirements for the strength, stability, serviceability, durability, and integrity of GFRP-reinforced concrete structures. Although adoption by authorities having jurisdiction (AHJ) will dictate when provisions become explicitly adopted in a particular area, these standards represent current state of the practice and can be used in the interim through an appropriate alternative means and methods process. ACI CODE 440.11-22 Building Code Requirements for Structural Concrete Reinforced with Glass Fiber-Reinforced Polymer (GFRP) Bars (440.11) will be referenced by the International Building Code (IBC) and ACI CODE 562-21 Assessment, Repair, and Rehabilitation of Existing Concrete Structures (562) will be referenced by the International Existing Building Code (IEBC). As of 2019 testing regarding GFRP based structures, there has been no loss of strength, whereas steel and similar materials lose their strength-based attributes after a few decades.The 2024 International Code Council model building codes will reference two additional American Concrete Institute (ACI) concrete design and construction standards. Another Benefitīeing a polymer, GFRP is able to withstand the extreme weather conditions and continuous rain and water submerged conditions. Especially in large structures, bridges, and buildings which are intended to last for a very long time. The use of GFRP instead of traditional steel is being used evidently. The use of traditional materials is decreasing and the use of new materials that can be recycled, reused and reduced consumption are being increasingly introduced. Most developed countries around the world are now relying on sustainable construction methods to save resources and provide buildings with a long service life. In this authors’ humble opinion, perhaps, the most influential material in construction today is Glass Fibre Reinforced Polymer (GFRP). One particular feature of this evolution is the construction materials used in the infrastructure of the cities we live in. ![]() Innovation that will assure the safety, sustainability and the survival of our future generations. This modernization of our development requires innovation as well. We are nowhere near the pinnacle of human evolution however the way we construct and build structures proves that our existence has gained a new level of livelihood and we are still moving forward. Low adoption among the construction professionals and preference for cost efficient project will restrain the industry growth. High initial costs due to the expensive processing and raw material prices may impact GFRP rebar manufacturers profitability. Rapid urbanization and industrialization leading to upgraded infrastructure and manufacturing facilities will support the product demand. For instance, China spent over 2.5 trillion AUD in 2019 on construction, while Japan spending registered over AUD 1 trillion in the same year. Increasing government budgets on construction and repairing in the emerging economies has positively influenced GFRP rebar market share. Highly durable GFRP rebar with leakage control and crack control properties acts as ideal reinforcement for underwater applications. Prevention from concrete cracks on the marine pillars caused due to alkali and chlorine content sea water occurrence will enhance product demand from marine structure. There are many future water treatment plants, marine structures, and MRI rooms application that will continue to propel the business growth in Australia.
