Cor-Tuf UHPC is excited to announce it is the exclusive licensed producer of Cor-Tuf Ultra-High Performance Concrete (UHPC) in the United States and the world. Cor-Tuf UHPC is an extremely strong and durable new concrete material developed by the U.S. Army Corps of Engineers (US patent No. US 8016938 B2) to fill a demand for a stronger and more resilient material to protect personnel and weapons facilities from blasts and intrusions.
After a rigorous application process, Cor-Tuf UHPC has been selected as the one and only licensed producer of the patented Cor-Tuf UHPC material for both the governmental and private sectors. The team at Cor-Tuf is proud to be able to make this innovative concrete technology available for use in all concrete projects, from bridge construction to highways and security.
Compositionally UHPC, in a general sense, is very similar to traditional concrete. What separates it into its own material classification is the addition of integrated fibers and a blend of proprietary ingredients which chemically change the make-up of the finished product to be stronger and more durable than conventional concrete.
Cor-Tuf UHPC separates itself from other UHPC products in this space by honing and refining the proprietary constituents which make up roughly twenty percent of its total composition (including fiber). These refinements impart several much-needed advancements into the product allowing Cor-Tuf UHPC to be pumpable, highly workable (up to 117 mins) and easily manufactured using the same conventional means and methods as common concrete.
Additionally, Cor-Tuf UHPC has a useful life of more than 75 years (versus 15 to 25 years for traditional concrete); resists environmental degradation; has a superior freeze/thaw resistance (more than 1,000 cycles—traditional concrete usually starts to degrade at about 27 cycles); and exhibits fire and moisture resistance (it’s waterproof).
Cor-Tuf UHPC also has a compressive strength from 28,000 psi to more than 116,000 pounds per square inch (psi), versus traditional concrete at 2,500 to 5,000 psi, and a tensile strength of 2,700 psi, versus 300 to 700 psi for regular concrete. Due to its strength, less material is required to create components typically made using traditional concrete allowing them to be lighter and more flexible in comparison.
Ideal uses for Cor-Tuf UHPC include field-cast connections in prefabricated bridge elements, bridge repair and maintenance, highway and infrastructure construction, pier pilings, airport runways, security enhancements, utility poles and all manner of concrete foundations. The product’s increased longevity and reduced maintenance requirements translate into a reduced life cycle cost for concrete structures.
The U.S. Federal government and many state governments strongly encourage the use of UHPC in many infrastructure projects through the Every Day Counts program, making the material a valuable choice in many bridge and highway projects. Cor-Tuf UHPC has already been used in bridge projects for the Virginia Department of Transportation.
The team will be batching several UHPC mixes and demonstrating the rapid manner in which the material comes together, its remarkable ease of placement, and its extended duration of workability on Tuesday, June 4th. Cor-Tuf looks forward to spreading knowledge around this innovative concrete technology as the future of the American infrastructure.
About Cor-Tuf UHPC
Cor-Tuf UHPC was founded in 2016. The company is the exclusive licensed producer of Cor-Tuf Ultra-High Performance Concrete (UHPC) in the United States. Cor-Tuf UHPC is a new concrete technology that is exceptionally strong and durable, displaying compressive strength of 30 times that of traditional concrete. This innovative concrete is impervious to water, demonstrates superior freeze/thaw resistance, and has a longer useful life of more than 75 years.
Cor-Tuf UHPC is replacing traditional concrete in such projects as bridge construction and repair, precast concrete deck panels, and field-cast connections between prefabricated bridge components. See the original press release on PRWeb here.
