Uses

Everything that traditional concrete can do—but better

Ready to pour? Speak to a concrete professional today.

Cor-Tuf UHPC is a revolutionary product that pushes the boundaries of what concrete can do. Our proprietary UHPC mix is the only one on the market that can be mass produced, mixed, and poured using conventional concrete machinery. All batches of Cor-Tuf UHPC meet our strict quality control standards, delivering a product that is consistently superior in strength and durability.

We are committed to bringing Cor-Tuf UHPC to the masses, making this groundbreaking concrete material appropriate for large infrastructure and defense projects to smaller buildings and precast elements.  

Precasting

Cor-Tuf UHPC is compatible with all contemporary precast methodologies, tools, and techniques. Cor-Tuf UHPC delivers the same benefits of traditional concrete while producing a highly superior product.

 

  • Mass produced in large batch plants
  • Mixed and transported in conventional ready-mix and Tuckerbilt trucks
  • Pourable into standard forms
  • Fully automated production process

Low Impact Design

Cor-Tuf UHPC is the premier material for Low Impact Design (LID). Reduced emissions and ground disturbance deliver cleaner and greener construction without sacrificing quality, durability, or environmentally sensitive areas where conservation is a key concern. Cor-Tuf UHPC lowers the cumulative carbon footprint of every project with:

 

  • Reduced transportation needs
  • Decreased Limits of Disturbance (LOD)
  • Smaller machinery for installation and transport
  • Reduced maintenance requirements

Accelerated Bridge Construction (ABC)

The same qualities that make Cor-Tuf UHPC ideal for precast elements deliver critical-path savings in ABC, retrofit, and modification projects. Cor-Tuf UHPC is extremely durable. Workers can install all day without losing time repairing breaks or replacing elements. Ideal for:

 

  • Cast-in-place joints between precast beams
  • Pre- and post-tensioning components
  • Injection or extrusion techniques (molding)
  • Link slabs between adjacent spans
  • Tilt-up construction

Defense and Security

Cor-Tuf UHPC was originally developed by the U.S. Army Corps of Engineers to protect personnel and weapon facilities. The combination of compressive strength, tensile strength, ductility, and impact resistance make the end product blast resistant. Ideal for:

  • Protection from debris impact from tornadoes and hurricanes
  • Thin concrete armor panels
  • Blast-resistant panels and bank vaults
  • Forced entry-resistant structure elements
  • Armored protective enclosures

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.
