3. INTRODUCTION
• High performance concrete is a concrete mixture, which possess high durability
and high strength when compared to conventional concrete.
• This concrete contains one or more of cementious materials such as fly ash, Silica
fume or ground granulated blast furnace slag and usually a super plasticizer.

4. What is High Performance Concrete?
• High Performance Concrete (HPC) is a specialized series of
concretes designed to provide several benefits in the
construction of concrete structures.
• Performance Benefits
• Cost & Other Benefits
4

5. Performance Benefits
• ease of placement and consolidation without affecting strength
• long-term mechanical properties
• early high strength
• toughness
• volume stability
• longer life in severe environments
5

6. Cost & Other Benefits
• less material
• fewer beams
• reduced maintenance
• extended life cycle
• aesthetics

7. Application
• BRIDGES
• HIGH RISE BUILDINGS
• TUNNELS
• PAVEMENTS
• NUCLEAR STRUCTURES

8. Objectives
• To put the concrete in to service at much earlier age, for example
opening the pavement at 3-days.
• To build high-rise buildings by reducing column sizes and increasing
available space.
• To build the superstructures of long-span bridges and to enhance the
durability of bridge decks.
• To satisfy the specific needs of special applications such as
durability, modulus of elasticity, and flexural strength. Some of these
applications include dams, grandstand roofs, marine foundations,
parking garages, and heavy industrial floors.

9. General Characteristics
• High strength
• High early strength
• High modulus of elasticity
• High abrasion resistance
• Low permeability and diffusion
• Resistance to chemical attack
• Volume stability
• Ease of placement
9

10. Advantages
• Longer spans and fewer beams for the same magnitude of loading.
• Reduced axial shortening of compression supporting members.
• Superior long term service performance under static, dynamic and
fatigue loading.
• Low creep and shrinkage.
• Greater stiffness as a result of a higher modulus Ec.
• Reduced maintenance and repairs.
• Smaller depreciation as a fixed cost.
10

11. Limitations
• High Performance Concrete has to be manufactured and placed much more
carefully than normal concrete.
• An extended quality control is required.
• In concrete plant and at delivery site, additional tests are required. This increases
the cost.
• Some special constituents are required which may not be available in the ready
mix concrete plants.

Completed UHPC Structures
• Sherbrooke bridge
• 1997
• Canada
• Seonyu bridge
• 2004
• South Korea
• Mars hill bridge
• 2006
• United States

13. Conclusion
• High performance, faster construction, reduced maintenance, longer
service life and low cost.
• A great accumulation of knowledge on the material, design, and
construction of UHPC structures have been gained with various
countries having attempted to introduce it to building and bridge
applications.
• HPC bridges provides efficient design longer span, fewer beams and
shallower structural depths.
