Special UHPC materials are virtually the bridge material of the future

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

      1. Was the bridge designed and manufactured by you?

      2. No we got a material specification for the UHPC bridge material from a consulting office. We made the material and gave it to the customer for testing. After the test was successful, we have made the necessary amount of material for the bridge. A precast plant then casted the individual bridge parts.
