Cor-Tuf UHPC Forms Partnership with Precast Systems Engineering

Cor-Tuf UHPC is excited to announce it has formalized an agreement with Precast Systems Engineering, LLC to help in the advancement of Ultra-High Performance Concrete.  

Cor-Tuf is the exclusive licensed producer of Cor-Tuf Ultra-High Performance Concrete (UHPC) in the United States and the world. Cor-Tuf UHPC is an extremely strong and durable new concrete material developed by the U.S. Army Corps of Engineers (U.S. patent No. U.S. 8016938 B2) to fill a demand for a stronger and more resilient material to protect personnel and weapons facilities from blasts and intrusions.

Cor-Tuf will help PSE develop the UHPC mixing technology for project-specific uses, using local supplemental constituents (sand, cement, and other materials as appropriate). PSE will support Cor-Tuf as a structural engineering resource to advance the technology and promote the continued development of Cor-Tuf.

“I have been excited for many months about how I envisioned the potential ‘union of forces’ between Cor-Tuf and Precast Systems Engineering,” says Rich Burgess, president of Cor-Tuf. “Our two companies have already started working together on several large projects and are in discussions concerning many more. We anticipate this new agreement will be mutually beneficial to both organizations. This is just the tip of the iceberg.”

About Cor-Tuf UHPC

Cor-Tuf UHPC was founded in 2016. The company is the exclusive licensed producer of Cor-Tuf Ultra High-Performance Concrete (UHPC) in the United States and the world. Cor-Tuf UHPC is a new concrete technology that is exceptionally strong and durable, displaying a compressive strength that is 10 times that of traditional concrete. This innovative concrete is impervious to water, demonstrates superior freeze/thaw resistance, and has a longer useful life of more than 75 years.

Cor-Tuf UHPC is replacing traditional concrete in such projects as bridge construction and repair, precast concrete deck panels, and field-cast connections between prefabricated bridge components.

About Precast Systems Engineering

JP Binard, a professional engineer registered in several states along the East Coast from New York to Florida, is the owner and manager of Precast Systems Engineering, LLC, specializing in construction engineering primarily focused on precast, prestressed concrete for buildings, marine structures, and bridges utilizing UHPC in components and connections.

The firm’s business model is based on teaming up directly with contractors, engineers, and owners in order to streamline fabrication or placement, facilitate communications throughout the design and casting process, and provide the best overall project delivery in terms of durability and performance.

Cor-Tuf UHPC Girder product being lifted
Cor-Tuf and Precast Systems Engineering teamed up at the Dura-Stress batch plant in Leesburg, FL for the most recent round of testing for Cor-Tuf UHPC.
The Cor-Tuf team is producing the second of two 30″x30″x30′ UHPC beams with ready mix trucks. The ready mix truck had no issues keeping up with the flow rate.
With the aid of the staff at Dura-Stress Inc., we can see the ready mix truck pouring into one of the very narrow openings in the top of the form for one of the two H-pilings.

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.
