Bi-directional PBO of 70+18 g/m² mesh for FRCM strengthening system with inorganic matrix
Pbo-Mesh 70/18 is an FRCM structural strengthening system with bidirectional PBO mesh and a stabilized inorganic matrix for reinforced concrete constructions. The structure of this PBO mesh makes it suitable for applications such as the wrapping of concrete columns or the reinforcement of beam-column nodes. This strengthening system does not use epoxy resins and its performance equals that of traditional FRP with carbo fibers and epoxy binder.
COMPONENTS OF THE SYSTEM:
Bi-directional PBO fiber mesh with 70 g/m²
in warp and 18 g/m² in weft available in two
- 50 cm (roll length equal to 15 m)
- 100 cm (roll length equal to 15 m).
Stabilized inorganic matrix specific
for applications on concrete supports
(in compliance with the EN 1504-3
PROPERTIES OF THE SYSTEM
- Increasing the flexural strength capacity of reinforced concrete beams.
- Increasing the strength capacity against combined axial and flexural forces in reinforced concrete columns.
- Increasing the strength capacity against shear of structural elements such as beams, joists in clay/concrete composite slabs, columns, and beam/column nodes.
- Increasing the strength capacity and ductility of non-confined reinforced concrete nodes.
- Increasing the strength capacity of the extremities of reinforced concrete columns.
- High system reliability thanks to post-cracking behaviour in detachment conditions.
- High system ductility and energy dissipation capacity.
- The system is also resistant to high temperatures and to freeze-thaw cycles.
- The inorganic matrix has very good adhesion to the concrete support.
- Simple and reliable placement of the inorganic matrix, which is laid in the same way as a traditional premixed bagged cement mortar.
- The system can also be applied to damp supports without any need for special protection.
- The mesh is easy to place and handle.
