a slow phenomenon under load - the fracture occurs when overloading on suddenly.
flexural and compressive forces. A chipping of the concrete structure of the inner steel reinforcement would have a very rapid component failure result.
- Extreme high compressive strength
- High flexural strength
- Extreme low porosity
- Extreme good flowability
- Fast increase of compressive strength (min. 70% after 48 hours)
- High wear and impact resistance
- Absolute frost and thaw resistance
- Impermeable to fluids but still vapour permeable
- Anticorrosive features
- Good bonding to sub-bases, aggregates and reinforcement
- High temperature resistant
- Jointless lining
- Usable as mortar, grout and spray
- High ductility in combination with fibres or nano fibres
- Usable with standard concrete tools
- Minor cracksRepair by injecting UHPC
- Buckled longitudinal reinforcement, broken ties and crushed concreteReplacement of new reinforcement welded with existing bars and new additionally closed ties were placed, UHPC concrete with low shrinkage properties installed.
- Severely damaged columns adjacent to added wallsRetrofitting with encasing in UHPC concrete with appropriate longitudinal and transfers reinforcement.
- Other columnsRetrofitted with wire mesh and cover with 50 mm UHPC concrete by spraying or casting
- Existing masonry wallsAre retrofitting by using wire mesh and 30 mm of UHPC® mortar or spray
A spalling of the concrete structure from the internal steel reinforcement would have a very fast component failure result.
