Getting the Mixer Set for Testing at CTL Labs

The Cor-Tuf team prepares to mix a batch of our UHPC, originally developed by the US Army Corps of Engineers. Testing has shown that UHPC has ten times the compressive strength of traditional concrete and a longevity of up to 75 years. Our team of experts is available to assist with any questions on the

Drop Test 1

Drop tests are used to demonstrate the durability of UHPC concrete. In our first drop test, a 16-pound bowling ball was dropped from 22.5 feet directly onto Cor-Tuf UHPC, cracking the bowling ball wide open. Cor-Tuf UHPC came out unscathed.

Drop Test 2

In our second drop test, a 67.5-pound cement block was dropped 22.5 feet onto Cor-Tuf UHPC. The cement block shattered on impact, while the Cor-Tuf slab remained intact.

VDOT Crew Pouring Cor-Tuf into a Precast Bridge Connection

As DOTs across the country implement accelerated bridge construction, precast bridge panels are becoming the norm. Filling panels with Cor-Tuf ensures that the connections between panels are stronger and more durable. This added strength reduces future maintenance needs, increases longevity, and most importantly, amplifies the cost savings achieved by decreasing the amount of downtime for

Mixing Cor-Tuf UHPC for Placement by VDOT in a New Bridge Installation

Many U.S. state governments strongly recommend that UHPC be used in all future bridge construction and repair projects. As a material provider, our service package revolves around mixing, delivering, and providing quality control for the on-site installation crew. Here, the team mixes Cor-Tuf in preparation for extremely durable field-cast connections for prefabricated bridge elements.

Pumping Cor-Tuf UHPC with a Standard TK-50 Commercial Pump

Despite industry misconceptions, Cor-Tuf UHPC can be pumped and poured just like conventional concrete—but with the added benefits of longer life, greater strength, and increased versatility. This makes it easy for any construction crew to use UHPC without bringing additional equipment onsite.

Mixer on its Way to the CTL Labs in Chicago

Ultra-High Performance Concrete is the ideal material to repair the more than 54,000 structurally deficient bridges in the US. Our rigorous testing, in partnership with CTL labs, demonstrates that Cor-Tuf UHPC is the best choice for rebuilding and reinforcing American infrastructure.
