Smarter Building Materials for a Cleaner Environment

Cor-Tuf UHPC

Cor-Tuf is a superior UHPC that develops exceptional strength and ductility dramatically higher than regular concrete. Its nominal strength, as shown in the table below, is generally 10 times the compressive strength of standard concrete. Additional mix techniques can be applied to raise that to in excess of 50,000 psi. Such mixes are typically suitable for applications requiring anti-ballistic resistance and protection of humans and sensitive property.

The tensile properties of Cor-Tuf are derived from the fiber integrated into the concrete mix. This can be varied from polyester to fiberglass bars, basalt, steel and stainless steel with escalating results in strength. The benefits of this strength are the potential to reduce structural designs engineered with regular concrete and significantly increased durability.

Re-engineering of standard concrete wall panel design with Cor-Tuf has demonstrated a reduction of 25% to 33% in wall thickness can be achieved – often without the need for rebar. This produces a reduction in material, weight and footing requirement for buildings. Which translates to reduced cost and increased efficiency in construction.

In addition, a considerable increase in the longevity of the application in turn increases the durability of any application. The estimated longevity of Cor-Tuf is 50 to 75 years.

Compressive Strength – 14 days 20,000 PSI
Compressive Strength – Fully cured, 28 days * 30,000 PSI
Tensile Strength 1,700 PSI
Modulus of Elasticity 6,000,000 PSI
*deviation +/- 10%

Cor-Tuf has the ability to be molded into any design, texture and shape. This means that period specific designs or demands for surface texture, color or shape can be provided. As a cast or molded material, Cor-Tuf can be poured into any mold that creates the appearance desired by the architect – masonry, wood siding, board & batted, textured concrete, etc. Cor-Tuf can be precast into any concrete shape or cast-in-place in response to the particular project design.

Cor-Tuf initially hardens in 2-3 hours and can be handled in about 8 hours following a pour. The cure time varies with temperature and humidity, but generally produces half-strength in 5-7 days. Full curing is in 28 days and results in the final strength noted in the table. Additional strength can be obtained with supplemental techniques that include the use of increased temperature, steam or both during curing, depending on the application.

Cor-Tuf also is very adhesive enabling it to stick to other components or other concrete in application. This makes it very adaptable for retrofit or modification of existing structures including parking garage decks, bridge decks, spalled structural members, building columns/walls to improve strength or protection and other applications.

Cor-Tuf is moisture resistant and impervious to environ- mental compromise from salts, chemicals and other hazards. As a result, the products of Cor-Tuf will not deteriorate, allow water through the cured material or be compromised by typical hazards encountered in the field.

Cor-Tuf truly is “the future of concrete”.
