Description
Adding external prestress through carbon reinforcement creates a reverse bending moment to the bending moment related to overloads and dead weight. This innovative process is protected by numerous patents.
The reverse moment generated by prestressing relieves the compression rate of the concrete and tension in the reinforcement. Thus, prestressing carbon strips achieves reinforcement levels impossible with passive carbon, considerably increasing the load-bearing capacity of a structural element, while having excellent control of its deformation.
Prestressing is achieved through a double set of permanent and temporary anchor plates. The prestress is applied by jacking. The temporary plates serve as temporary support for the prestress until the resin sets.
This process is mainly used to reinforce beams and floor slabs of all types, bridge decks, or to band reservoirs or silos. This type of reinforcement allows:
- Increased strength
- Reduced deformation
- Reduced cracking
- Reduced fatigue
