High Performance Concrete
Ultra-High Performance Concrete (UHPC)
UHPC is a new class of concrete that is extremely strong and durable. UHPC is very similar to traditional concrete, but roughly 25 percent of its composition is composed of a variety fibers and mineral/ chemical additives that create a significantly stronger end product. The integrated fibers vary from polyester to fiberglass, basalt and steel, with each bringing its own unique advantages.
UHPC has an estimated lifespan of more than 75 years compared to 25-35 years for traditional concrete. It also has a compressive strength of 30,000 pounds per square inch (psi), with some mixtures achieving 100,000 psi. Traditional concrete has a compressive strength of just 4,000 psi.
Other benefits of UHPC include flexibility, ductility, and extraordinary resistance to salt, moisture and chemicals. All of these remarkable improvements result in a projected dramatic increase in the life cycle of infrastructure constructed with Cor-Tuf UHPC as a major component. The properties of this concrete make it ideal for traditional applications, as well as newer and more advanced uses in areas such as architectural design, which require thinner components and complex shapes.
