Learning Objectives:

Upon completing this program, the participant should know:

1. What is Ultra-High Performance Ductile Concrete?

2. Where and how it is used.

3. How to develop new solutions with UHP Ductile Concrete

4. How it will be used in the future.

What is Ultra-High Performance Concrete?

• UHPC is produced with materials commonly found in concrete (cement,silica fume, sand, superplasticizer and water) plus unique materials likeground quartz and fibers (high carbon metallic or poly-vinyl alcohol [PVA]).

• The fiber and UHPC chemicalformulation is customized tobest fit application requirements.Factors include strength andrheology requirements, exposure

to corrosive agents, desiredaesthetics and exposure tohuman contact.

• Not all UHPC’s are EQUAL!




• A technological breakthrough

• Superior characteristics include:

– ultra-high strength

– ductility

– durability

– highly moldable/flowable/dry-cast

• excellent form replication

– aesthetic design flexibility, quality surface aspect


• “Materials with a cement matrix & characteristiccompressive strength in excess of 22,000 psi,possibly attaining 36,000 psi, and containingfibers in order to achieve ductile behavior undertension and, if possible, to dispense withpassive (non-prestressed) reinforcement.”(1)

• “UHPFRC differs from HPC by:

– compressive strength > 22,000 psi (150 MPa);

– systematic use of fibers to ensure non-brittle, and;

– high binder content & special aggregates.”(1)

(1) Source; SETRA “UHPFRC Recommendations”, January 2002.



It Can Provide:

• Compressive strengths up to 30,000 psi;

• Flexural strengths up to 6,000 psi;

• Direct tension up to 1,450 psi;

• Ductility;

• greater capacity to deform and support flexural

and tensile loads, even after initial cracking.

• Abrasion resistance similar to natural rock and;

• Impermeability

• almost no carbonation or penetration of chlorides

Note: Not all UHPCs provide all of these properties.

The Future…

• The future of this material technology is limited only by the imagination ofarchitects, engineers, builders and entrepreneurs.

• As new, complimentary equipment and tools are developed, the materialtechnology will flourish.

• Shells/decks/panels

• Longer, more

graceful spans

• Higher, more

slender structures
