Bridges are among the oldest, most important and most prominent construction tasks of humanity. For a long time, bridge construction was mainly characterised by functional criteria, but nowadays more and more attention is paid to visual appearance. Highly developed building technologies can be used to create exciting, previously unimaginable constructions.Several characteristics of UHPC make it a desirable construction materials. With increased compressive (more than 200 MPa) and tensile
strengths, the material lends itself well to
structural applications by allowing higher loads
to be supported. By utilising the higher strengths,
traditional structural components can also be
reduced in size and weigth.
Another benefit of UHPC is the high density and
none porosity of the material making it essentially
impermeable to water and chlorides, thus making
the material highly durable. Both characteristics
also make UHPC attractive in areas of high impact
and where water or chloride ions can corrode steel
reinforcement.
Advantages
- High compressive strength
- Fast development of compressive strength
- High wear and impact resistant
- Absolute frost and thaw resistant
- Impermeable to fluids but still vapour permeable
- Anti corrosive features
- Good bonding to sub-bases, aggregates and reinforcement
- High temperature resistant
- Fast curing
- Sort repair stops
- Jointless lining
Elements of a bridge that can be executed with UHPC
- Bridge foundation
- Bridge bearings
- Bridge supports
- Bridge deck and bridge deck pavement
- Prestressed concrete foundation
