There are many benefits to using FRP rebar in reinforced concrete projects. When we compare traditional steel reinforcement to FRP rebar, it is clear FRP rebar is the more efficient choice in all applications. Let’s explore the different ways that FRP rebar can be used.
Bridges, Barrier Walls and Decks
One of the most popular FRP rebar applications are bridges, barrier walls, and decks. These specific types of structure require materials that are non-corrosive and are long-lasting, which are both features of FRP rebar. These are important benefits compared to traditional steel reinforced infrastructure projects which have a shorter lifespan, and an increased repair cost. Along with the fact that FRP rebar is 1/4th the weight of steel rebar making it incredibly lightweight, safer, and easier to install, it is clearly the best choice for reinforcing concrete.
Pavements, Multi-Storey Parking Garages, Roads and Balconies
We often see deterioration that is caused by the corrosion of the reinforced steel in multi-level parking garages. This issue can also be found in balconies and roads because these structures are constantly exposed to harsh elements. In contrast, FRP rebar are corrosion resistant, they take less time to install, they don’t require continuous repairs, they are competitively priced, making them the wiser choice for reinforcing cement that withstands a variety of environmental factors and conditions.
Diaphragm Walls and Foundation Pit Retaining Piles
When it comes to using tunnel boring machines (TBM) for your next tunnel project, it is important to remember that TBMs are not best suited for handling steel reinforced concrete structures because of the resilience of the steel. The ductility of steel will impact the rotary cutters by absorbing the cutter’s energy. The cuttability of FRP rebar is much easier, and the GFRP reinforced concrete launch box is a much better solution compared to steel. FRP rebar is flexible, lightweight, non-corrosive, durable, and is high end loading making it the perfect choice for diaphragm walls and foundation pit retaining piles.
Precast Tunnel Segments
Using steel rebar to reinforce precast tunnel segments has many downsides because of its low structural durability and high weight of the segments for transporting, unlike FRP rebar which is ¼ of the weight of steel rebar. Steel reinforcement can create electric joints, which can lead to corrosion problems, something that FRP rebar is superior in because it is non-corrosive with dielectric joints. FRP rebar can also be used as a temporary or permanent application, because it can be demolished later, making it an easy solution for precast tunnel segments.
Mining Roadway Support and Tunnels with Rock Bolts
When it comes to using steel bolts, it is important to remember that they are difficult to cut by mining machines and can cause fires and explosions in gas and coal mines. That is why when working on tunnel projects in corrosive environments, FRP rebar is superior to steel because it is corrosion-resistant, easier for mining machines to cut, and much more durable for reinforced concrete structures. FRP is also ideal in these cases because it is anti-static and explosion proof, with high tensile strength, and lightweight making it easy to install.
Wharfs, Sea Walls, Wave Breakers and Water Treatment Plants
When building your concrete structure in marine or chemical projects, there can often be deterioration caused by the migration of chloride ions that lead to steel corrosion. To avoid this very major problem, using a lasting and durable FRP rebar is the best solution. FRP rebar is completely unaffected by chloride ions, has a high tensile strength, and is easy to handle, making them the best option for any marine or waterside concrete reinforced project.
FRP rebar is the best solution for reinforced concrete projects when compared to traditional steel rebar. Being non-corrosive, long-lasting, durable, non-conductive, lightweight, and with a high tensile strength, are just a few of the benefits of FRP rebar. Moreover, FRP can be recycled making it a greener alternative as well. FRP rebar is clearly the smart choice for all reinforced concrete projects.
