In FRP fabric systems (sheets), the polymer resin (usually epoxy resin) is utilized as a primer, putty coat, and saturant in externally bonded applications. To serve as an adhesive between the FRP system and the concrete surface, the resin is primed onto the surface of the element.FRP strengthening solutions are engineered, specified and installed to solve a host of structural deficiencies or demands in existing structures:
Durability problems due to poor or inappropriate construction materials.
Inadequate design or construction.
Increased loading requirements due to code or use changes.
FRPs (Fiber Reinforced Polymers) are composite materials made of a polymer reinforced with fibers. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic that is combined with a fiber, such as glass or carbon, in order to make the polymer strong and stiff.
What is structural strengthening using fiber reinforced polymers : Fiber reinforced polymers (FRP) are a proven technology for upgrading and strengthening concrete, masonry, and steel structures. These advanced composite materials have exceptionally high strengths, yet are very lightweight and easy to work with.
What is the purpose of FRP
Fiberglass-reinforced polymer is a strong, lightweight building material that resists corrosion. FRP is sometimes called composite because it's made of a combination of materials that work together for even stronger performance.
Why do we use FRP : FRP can be used in a wide range of applications but is commonly used in construction as panels. Used as a panel it can create strong walls and surfaces that are scratch-resistant and able to withstand high impacts. FRP is commonly used in schools, hospitals, recreational facilities and other industrial settings.
Here are some of the beneficial features of FRP composites:
Lightweight compared to most metals.
Corrosion-resistant.
High impact strength.
Electrical insulation.
Easy installation.
Low maintenance.
Exceptional durability.
Fiber-reinforced polymer composite offers not only high strength to weight ratio, but also reveals exceptional properties such as high durability; stiffness; damping property; flexural strength; and resistance to corrosion, wear, impact, and fire.

Advantages: FRP-reinforced concrete structures have high strength, durability, and corrosion resistance. Disadvantages: FRP may lose strength and stiffness at high temperatures, especially when approaching the glass transition temperature of the resin.What are the disadvantages of using fiber-reinforced concrete
Must be mixed carefully. The fibers used in fiber-reinforced concrete must be dispersed meticulously and uniform throughout the concrete mix.
Cost. Compared to non-reinforced concrete, fiber-reinforced concrete is more expensive.
Weight.
Fibre-reinforced plastics are best suited for any design program that demands weight savings, precision engineering, definite tolerances, and the simplification of parts in both production and operation.
What is the use of FRP : FRP is used in designs that require a measure of strength or modulus of elasticity for which non-reinforced plastics and other material choices are ill-suited, either mechanically or economically.
Why is FRP better : FRP products are known for their high strength-to-weight ratio, providing excellent structural strength while being lightweight. They have high durability and can withstand harsh environmental conditions, including exposure to chemicals, UV radiation, and extreme temperatures.
Is fiber reinforced concrete better
Fiber mesh reinforcement significantly improves the flexural strength of concrete, which is essential for driveways that endure heavy vehicle loads and surface movement (like frost heaving). By adding macrofibers to the concrete mix, fiber reinforcement prevents cracking and enhances overall durability. Steel Fibers: These fibers are generally used for providing concrete with enhanced toughness and post-crack load carrying capacity.Poor long-term temperature resistance. FRP cannot be used under high temperature for a long time, the strength of polyester FRP decreases obviously when it is above 50℃, and it is generally only used under 100℃. The strength of epoxy FRP decreases obviously above 60℃.
