This close-up shows the solid consistency of Cor-Tuf UHPC, making the beam impermeable to moisture. While the fine-grained nature of the mix allows for a
This view “inside” the “H” shows the beam’s smooth surface. Cor-Tuf hardens within two to three hours and can be handled in eight hours following
Cor-Tuf UHPC is a proprietary UHPC mix that overcomes all of the barriers associated with conventional UHPC products. It can be mixed, transported, and poured just as you would traditional concrete—even using the same machinery. But what does this mean for your next concrete project? Are there additional benefits to choosing Cor-Tuf UHPC over a conventional UHPC mix?
Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 21,500 pounds per square inch (psi). UHPC is
is the world’s preeminent authority on concrete research and industry standards. Based in Michigan and founded in 1904, ACI develops technical standards and certification criteria for the production, installation, and maintenance of concrete. Building and design codes at the local, state, federal, and international levels increasingly rely on ACI publications to establish specifications for concrete construction.
The use of ultra-high-performance concrete is becoming more common, thanks in no small part to the fact that it can now be mixed, transported, and poured using standard ready-mix trucks. The cost is also coming down, because you don’t need to buy a concrete manufacturer’s sand or cement; you can use your own. More on that in a bit.
The cost of construction materials can be just as important as the quality. Ultra High-Performance Concrete (UHPC) checks all the boxes for quality, but many still worry that the price is too high. The question on everyone’s mind seems to be: “When will the cost of UHPC come down?”
More than 30 years of research and recent commercial success have proven the promise of Ultra-High Performance Concrete (UHPC). Its strength and durability have brought UHPC into the spotlight for public agencies and private firms seeking superior alternatives for concrete construction.
Conventional concrete is all around us for a reason. Its workability and performance have been honed by construction crews for generations, used for everything from bridges to building columns to airport runways to two-seater park benches. The success of concrete is built on industry know-how and methods that work.
