UHPC is here to stay and everyone should benefit from it

At HiPer Fiber, we believe in the power of collaboration and open development. That's why we share our open Ultra-High Performance Concrete (UHPC) formula, which provides a solid foundation for others to build upon and innovate.

Notes

Create your custom UHPC with HiPer Fibers

   * - High demand applications, such as blast and impact loading, would tend to require 2% by 
       volume, the remaining all other applications, e.g. traffic loading on bridges, 1.5% by volume. 
      Dosage can be increased to address extreme loading conditions.

  1. Water/cement ratio is 0.23. If it is hot (say above 80 degrees ambient temperature), you could use ice (20% - 40% of water) to aid in mixing. 

  2. If you use Elkem 900W or a light colored silica fume, you may need to reduce the HRWR a bit

  3. Batch trial is recommended

  4. This information is not warrantied. You must conduct your own testing to ascertain performance. 

Mix Protocol 

Create your custom UHPC with HiPer Fibers

  1. Dry mix: 10 minutes. Add water and HRWR over 2 minutes

  2. Wait for turnover (fluidity), which usually occurs within 15 minutes 

  3. Mix another 10 minutes after turnover

  4. Add fibers gradually over 2 minutes

  5. Mix for ten minutes then cast.
