What makes concrete Ultra-High Performance?

  • High compressive strengths (> 120 MPa or 18ksi)
  • Post-cracking ductility (strain-hardening material)
  • Extremely High Durability (low permeability and discontinuous pore structure)
  • Superior bond strength to reinforcement (reduce joints from 30″+ to 7″)
  • Improved interface bond strength to facilitate composite connection
  • Excellent workability (self-consolidating material)
  • Advance material durability and toughness
  • Increased abrasion resistance
  • High freeze-thaw resistance
Are there multiple types of UHPC? Yes! UHPC specifications can be modified to fit the criteria that will most benefit the finished structure.  Consult a UHPC expert to be sure to cater your specification and material properties to best fit your application! Proper planning in design of specification and material properties requested for a project can:
  • Reduce the overall volume of material for the project
  • Reduce the time to completion of the project
  • Reduce the overall cost of the project
  • High Early Compressive Strength – for an Accelerated Bridge Construction (ABC) where you need to replace the bridge in 96 hours, requiring high early strength concrete is a must. It takes UHPC-type material only 6 hours to achieve the same level of compressive strength as it takes normal concrete 28 days to develop!

While UHPC has been under research and development globally for a half of a century, it is still a relatively new material technology compared to conventional concrete. Today the use of this technology is rapidly increasing and gaining acceptance in numerous applications, such as bridges, architectural products, windfarms, water / waste-water, building elements and others throughout the world. It is the superior mechanical properties of UHPC, particularly durability and ductility that provide the benefits and reasons for uses of this material globally.
