Ans:

• Strength: Composite reinforcement is 2-3 times stronger than steel reinforcement.
• Durability: Its thermal expansion matches concrete, preventing microcracks and enhancing structure longevity.
• Corrosion Resistance: Unlike steel, GFRP rebars are 100% corrosion-resistant with a lifespan exceeding 80 years, even in aggressive environments.
• Lightweight: Composite reinforcement is 4 times lighter than steel, with comparable strength.
• Low Thermal Conductivity: Reduces thermal loss by 34%, lowering building conditioning costs.
• Easy Installation: Can be cut to any length, speeding up site work, and fastened using plastic clips, clamps, or binding wires.
• Easy Transportation & Storage: Foldable into coils for transport, allowing cost-effective delivery even via small vehicles. Its low density (1.9 Tons/m³) enables loading 4 times more material, cutting logistics costs significantly.
• Custom Length: Available in custom lengths, eliminating overlaps, reducing material waste, time, and labor costs.

Ans: Yes, you can use GFRP Rebars together with metal rebars in some cases where it is necessary.

Ans:

• Modulus of Elasticity: The modulus of elasticity of composite reinforcement is almost 4 times lower than that of metal reinforcement, even with an equal diameter. It easily bends. For this reason, it is mostly used in ground applications, where usage in floors requires additional calculations.
• Dielectric: Composite reinforcement, unlike metal reinforcement, cannot be welded by electric welding.
• Temperature: When heated to a temperature of 600°C, the compound that binds the composite reinforcement fibers softens so much that the reinforcement loses its elasticity. Additional measures should be taken to heat protect the structures using composite reinforcement in fire-prone areas.
• Bending: Composite reinforcement does not have the mechanical elastic properties of metal reinforcement, thus it cannot be bent on-site.

Ans: Due to higher fatigue properties, GFRP Rebars have a higher resistance to cyclical loads of high intensity, which makes GFRP Rebars workable during earthquakes subject to a detailed design report on the same.

Ans: When reinforcing concrete/cement structures with GFRP Rebars, special requirements to the components of the concrete mixture (cement, aggregates, additives) are not presented. It is also possible to use composite reinforcement with Portland cement and its varieties (sulfate resistant, hydrophobic etc.). The quality of concrete mixtures and the technology of their preparation should ensure the production of concrete structures that meet the requirements for standardized quality indicators.
