Cor-Tuf UHPC Launches New Website: See This Revolutionary UHPC in Action

Cor-Tuf UHPC, the first and only licensed producer of Cor-Tuf Ultra-High Performance Concrete (UHPC) in the United States and the world, is making it easier than ever to see all of the unique abilities of Cor-Tuf UHPC. The company’s new website puts visitors one click away from getting started on their next concrete construction project with this ultra-high performance concrete material that can do everything traditional concrete can do—only better.

Cor-Tuf UHPC is introducing a host of new features that make it simple and quick to learn about (and see) this revolutionary concrete material in action. A video section showcases work Cor-Tuf has completed on recent projects, tests that demonstrate the strength and durability of the product, and up-close footage showing how easy it is to use Cor-Tuf UHPC on the job site. The company has also added a gallery section displaying photos from their latest installation projects and tests, so visitors can get a closer look at the unique capabilities of this versatile and contractor-friendly material.

Construction professionals can get started with Cor-Tuf using a project submission form, accessible from any page on the site. This makes it simple and convenient to submit project specifications, ask questions, and begin working with Cor-Tuf UHPC. “We are committed to helping contractors, engineers, architects, and other professionals understand the many benefits Cor-Tuf UHPC brings to projects,” says Rich Burgess, president of Cor-Tuf. “The videos and gallery on the new website show the many new and innovative uses Cor-Tuf makes possible for concrete.”

Cor-Tuf UHPC is a proprietary UHPC concrete mix that was originally developed by the US Army Corps of Engineers. This ultra-high performance concrete delivers extreme strength and durability. Unlike conventional UHPC mixes, Cor-Tuf UHPC is extremely unique and versatile.

In fact, Cor-Tuf UHPC is an ideal replacement for steel on many projects, delivering the same performance capabilities and strength of steel with smaller components. Reduced material requirements translate into direct cost savings. Smaller components can be transported and installed with smaller machinery and fewer workers, adding to cost savings and reducing the overall project’s carbon footprint. Reduced emissions and ground disturbance make Cor-Tuf the ideal material for Low Impact Design (LID).

Unlike steel, Cor-Tuf UHPC is resistant to environmental degradation and impermeable to air and water, so the product will not rust, oxidize, or deteriorate. It is a superior material for use in all marine environments. A product lifespan of roughly 100 years makes Cor-Tuf UHPC an incredibly cost-effective replacement for steel on any project.

Cor-Tuf UHPC can be manufactured, transported, and installed with traditional concrete machinery. It is pourable and pumpable, and it can be mass produced. With a working time of approximately 100 minutes, the material can be used on any construction project where workers would normally use traditional concrete or even steel.

Other uses for Cor-Tuf UHPC include precasting, accelerated bridge construction, and defense and security applications. Cor-Tuf is compatible with all contemporary precast methodologies, tools, and techniques. It delivers critical-path savings in accelerated bridge construction, retrofit, and modification projects, with workers able to install all day long without losing time repairing breaks. Cor-Tuf is blast- and impact-resistant, making it an excellent material for protection against debris from natural disasters, bank vaults, and protective enclosures.

Cor-Tuf UHPC is the future of concrete. Contractors and others working on concrete structures are welcome to dive into all of the interactive resources that have been added to the newly designed website.

What Makes UHPC Ultra-High Performance

UHPC achieves its superior performance through a dense nano-scale matrix that is far less permeable than conventional concrete. This matrix is combined with steel fiber reinforcement, which provides exceptional ductility and crack resistance.

Though exact formulations and results vary by producer, UHPC generally incorporates a blend of Portland cement, sand, supplementary cementitious materials, chemical admixtures, and fibers – resulting in a material dramatically stronger, tougher, and longer lasting than traditional concrete.
