External carbon fiber reinforcement is used in various situations where strengthening is necessary. It is extremely suitable for structural reinforcement, crack repair, and seismic strengthening. In commercial buildings and infrastructure, among others, this technique can contribute to strengthening existing structures without significant weight increase. Additionally, this technique is widely applied in hospitals, where the integrity and safety of structures are of utmost importance.
We apply this technique when the live load (the weight on the structure, for example from furniture or vehicles) on beams, floors, and bridges is increased. Applications can range from floor reinforcements for new stairwells to increasing the load-bearing capacity of traffic viaducts. A plaster layer and/or fire-resistant coating can subsequently be applied over the adhesive reinforcement.
Advantages of External Adhesive Reinforcement
Thanks to the combination of very high strengths and low self-weight, the carbon fiber adhesive reinforcement can be easily placed to ensure the strengthening of the concrete structure. Carbon fiber is significantly lighter than traditional materials such as steel, thus barely burdening the structure. Moreover, it is resistant to corrosion, which extends the lifespan of the reinforced structures. The flexibility of the material makes it possible to apply it to various surfaces and shapes, contributing to the versatility of this technique.
When is carbon-fiber bonded reinforcement the right solution?
- When changes or improvements to existing structures are required.
- When removing walls or columns.
- When there is insufficient reinforcement or concrete cover.
- When the concrete structure has been damaged due to mechanical overloading, fire, or other incidents.
Adhesive-bonded CFRP reinforcement, or a variant thereof, is used in situations such as:
- When imposed loads on structural elements increase.
- When changes or modifications are made to the load-bearing structure.
- In cases of damage such as fire, mechanical overloading, or other incidents.
- For structural modifications where traditional strengthening of the concrete structure is not an option due to accessibility or other constraints.
