See Cor-Tuf UHPC in action

Ready to pour? Speak to a concrete professional today.

There is no better way to appreciate the many ways Cor-Tuf UHPC is revolutionizing the concrete industry than by watching the product in action. Our video collection features a range of content, from Cor-Tuf UHPC being produced and poured using traditional concrete machinery to live-action tests demonstrating the product’s superior durability and strength. Take a look and see exactly what Cor-Tuf UHPC can do for you on your next concrete construction project

See It In Action: Cor-Tuf Ready-Mix UHPC Overlay

Cor-Tuf is proud to present our latest product offering, the Cor-Tuf Ready-Mix UHPC Overlay. Taking advantage of the growing UHPC market is as easy as mixing your sand, your cement and our UPHC in the same ready-mix equipment you already own!!

Cor-Tuf UHPC Ready-Mix Demo

Gone are the days of large lay-down areas, bulky on-site mixers, and sizable footprints they typically occupy. In this video Cor-Tuf UHPC performs a proof of concept demonstration of how our CT-25 product can be mixed in a ready-mix truck for mobile delivery directly into an on-site form, pump or other distribution method.

Cor-Tuf UHPC Mobile Batch Plant

Our new fully-automated mobile concrete batching plant for Cor-Tuf UHPC has been tested at Dura-Stress, Inc., in Leesburg, FL and is ready for operation. See for yourself how this well-engineered portable batch plant solves the problem of onsite mass production. This results in a consistent process that can be certified by a printed batch ticket for every load produced.

Cor-Tuf UHPC Bridge Closure

In this video, we use Cor-Tuf UHPC to complete a RT-64 bridge closure in Richmond, VA. By pouring Cor-Tuf UHPC in the joints between bridge deck panels, the structure is solidified, strengthened, and fused together

H-Piling Creation and Installation

In this Cor-Tuf UHPC video, we demonstrate the creation and installation of the next major advancement in pre-tensioned ultra-high performance concrete structural components: our full-scale Cor-Tuf UHPC H-Piling.

Cor-Tuf UHPC H-Piling Tests

In this Cor-Tuf UHPC three-day testing event, we poured two 30′ beams, one 63′ beam and two 30′ H pilings. We also demonstrated the user friendliness of the product by producing all of the components with industry standard ready-mix trucks.

Cor-Tuf UHPC Piling Life Cycle

Here’s a video walk-through of our recent production and testing of three UHPC pilings. All three pilings were poured using conventional large-scale means and methods common to the concrete industry, and were tested in partnership with the Florida Department of Transportation.

Cor-Tuf UHPC Piling Pour Test Part 1

In our first round of testing at Dura-Stress, Inc. in Leesburg, FL, we prove that Cor-Tuf UHPC components are by far the strongest on the market and can easily withstand the continuous stress of piling installation into the ground. Our pretension pilings are free of voids and can be mass produced using conventional large-scale means and methods common to the industry.

Cor-Tuf UHPC Drop Testing Concrete Strength

Watch as we drop a bowling ball 22 feet and a 67-pound concrete block 22 feet to test the strength of Cor-Tuf UHPC. See how well our concrete held up!

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.
