Repair, maitenance & rehabilitation

Would you be kind enough to suggest me possible techniques to repair, strenghen concrete beams (linear elements)

Your expert opinion will be a courage for me.

RE: Repair, maitenance & rehabilitation

Several techniques are available to repair and strengthen reinforced concrete.  The problem will be choosing the one that fixes the problem, causes the least disruption to service, and costs the least.

If the beam is fully accessible and temporary shoring can be erected to unload the beam, all or part of the beam can be removed and then new concrete placed along with appropriate dowels and additional reinforcing steel.

Other techniques that may be useful, but also have limitations include: epoxy injection of cracks, attaching fiber reinforced composite (FRP) material on the exterior faces of the beam, adding new support members to change the loading conditions of the beam, fully casing the existing beam with new reinforced concrete, "stapling" across cracks with structural steel bolted through drilled holes in the beam, etc.

The possibilities really are quite extensive, but the most important thing to realize is that if a repair is made, but the problem that caused the need for that repair in the first place is not identified and fixed, then the repaired beam will eventually end up in the same state again (needing another repair).

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
