About the Product Process with Steelike® UHPC
For infrastructure projects, Steelike® UHPC is typically mixed on-site in accordance with directions provided by Steelike‘s Technical Support team. The following is an overview of the typical on-site process when working with Steelieke® UHPC.
|Flexible Mixing Options Support Customer Work Site Needs: Only Steelieke® UHPC offers our customers product mixing options that save costs in terms of time, labor and equipment. Innovative mixing options provide flexibility to better support specific project and job site needs.|
Off-Site Mixing: Steelieke® UHPC may be mixed off-site in a standard front loading ready-mix truck and then delivered to the project location. This option reduces work site disruptions and space requirements.
On-Site Mixing: Steelieke® UHPC may be mixed at the job location in a standard front loading ready-mix truck or in a variety of other mixing equipment.
For precast deck-level connections, Steelike UHPC can be placed flush with the surrounding deck. Whereas competing products require overfilling to grind away a top layer that gets filled with air bubbles, Steelike has a unique proprietary process to prevent the accumulation of air bubbles.
Steelike UHPC should be maintained at a minimum curing temperature of 50° F (18° C). Steelike has the capability to determine the in-place strength of the Steelike UHPC using embedded sensors without solely relying on breaking cylinder or cube samples.
For a bridge deck overlay application, to achieve a desirable surface profile and adequate skid resistance, the top of an overlay is typically grinded and/or grooved.
Any formed surface of Steelike UHPC will replicate the texture of the form to a high level of detail, which can be advantageous for architectural and decorative applications.
Frequently Asked Questions about UHPC
Are you new to UHPC? These are questions are commonly asked questions about UHPC from FHWA website UHPC FAQs, last updated December 2019.
Concrete is a composite material made from coarse aggregate (rocks), fine aggregate (sand), portland cement, and water. When mixed, the portland cement and water combine together in a chemical reaction to create the glue that holds together the aggregates. Concrete starts as a semi-liquid that can be placed or formed. It hardens over time to create a solid that is similar to rock.
Ultra-high performance concrete (UHPC) is a class of concrete that combines together many of the recent advances in concrete science to create a material with far superior properties. In the fresh state it is more fluid than regular concrete thus making it easier to place into the formwork. In the hardened state it is much stronger than regular concrete. It also contains a large amount of randomly distributed steel fibers that help the UHPC maintain its load-carrying capacity even after overloads or in aggressive environments. Finally, the UHPC is much less permeable than regular concrete and thus the UHPC is far less likely to degrade due to freeze-thaw action or corrosion of embedded reinforcing steel.
Imagine that you added a hundred pounds of needles to every ton of concrete. These needles would be randomly distributed throughout the concrete and would help to reinforce it on a micro scale. In practice, about 2 percent of the volume of a UHPC product is steel fibers. These fibers are usually small diameter steel wires that are cut to be less than 1 inch long. The fibers stitch together the UHPC so that, even if the UHPC experiences a large load that causes it to crack, the fibers will allow the UHPC to continue to resist the load.
The normal concretes used today in highway bridges are designed to offer better performance than “sidewalk” concrete, but are prone to cracking and degradation primarily due to corrosion of the embedded reinforcing bars. UHPC offers much superior durability. Through its enhanced strength, it also allows for optimization of the design of the structure. UHPC structures can be easier to construct and can create opportunities to reduce the normal reliance on large volumes of field-cast concrete.
FHWA plays a leading role in bringing innovative solutions to the highway infrastructure sector. By and large, State Departments of Transportation own and operate the infrastructure, but their perspective may not extend to national and international best practices and innovative ideas. FHWA recognized the potential in UHPC in the early 2000s and has, through their research arm at the Turner-Fairbank Highway Research Center, focused on developing deployable solutions that make use of the best that this technology has to offer.
The simple answer is cost. Normal concretes cost a few pennies per pound, while the price of UHPC is more like a half dollar per pound. In short, the constituents in UHPC cost more.
For this reason it is important to use the UHPC in critical locations where its benefits reduce short and long term costs elsewhere. Moving forward, it is expected that the cost of UHPC will reduce as the technology matures.
The technological advancements inherent in UHPC both will afford direct solutions to today’s infrastructure challenges and will be integrated into the normal concretes of tomorrow. One of the biggest opportunities for UHPC will be to rehabilitate and harden the highway infrastructure against the insidious effects of traffic loads, an unforgiving environment, and time. UHPC has the potential to allow for the long-term rehabilitation of road and bridge surfaces without requiring full reconstruction. It can also allow for the repair of substandard infrastructure in a way that meets current design requirements while minimally impacting the operation of the facility. Most importantly, it can open the door to longer service lives with reduced need for repair and thus reduced impact on the traveling public.

Finally, the unique 100% preblended dry mix results in an extremely smooth and highly consistent material flow, further facilitating the casting of ultra-thin components and creating highly predictable mixing and casting conditions well suited for a repetitive production environment. Bill Kulish, the inventor of Steelike UHPC, created the formula with architectural applications in mind, and has demonstrated the material’s versatility as a medium for design expressions through many proofs of concepts.
Ready-mix trucks are widely available and relatively affordable to rent. This typically saves contractors money compared to renting and setting up specialty mixers from other UHPC suppliers. In addition, a single truck can mix 4 times as much as the typical largest specialty mixer, resulting in less time spent waiting for fresh UHPC to be mixed. Finally, for projects in congested locations, Steelike UHPC can be mixed offsite and driven onto the project site for discharge.
