Lafarge is a partner of the France Pavilion at the Shanghai 2010 World Expo. The Expo is focusing on themes of urbanization, architecture and sustainable construction. The "Seven Wonders of Concrete" presentation illustrates the most spectacular technological initiatives in terms of building materials through symbolic structures. From June 7th, come and vote on our Facebook page for your favorite structure. The structure which wins the most likes will be named Top Wonder of Concrete!

The France Pavilion at 2010 World Expo, in China
Conceived and designed by architect Jacques Ferrier, the Pavilion is a symbol of
innovative French engineering. Outside the Pavilion, this expertise is illustrated
by a concrete mesh - a symbol of power and refinement, encircling it and
appearing to float above a lake.

The France Pavilion at 2010 World Expo, in China
The Pavilion is based around the concept of the “Sensual City”. Lafarge’s area is
dedicated to touch. Made from Ductal® concrete, it is decorated with numerous
small multi-colored squares combining photos and samples of decorative
concrete.

The Peace Footbridge, in South Korea
The Peace Footbridge, designed by Rudy Ricciotti, crosses the Han River to link
the island of Sunyudo to the center of Seoul. It was built in 2002 with ultra-high
performance fiber-reinforced Ductal® concrete.

5. #2
The Peace Footbridge, in South Korea
"This footbridge has a span of 130 meters but the deck (horizontal platform) is
only 3 cm thick!" architect Rudy Ricciotti points out. This exceptional feat was
made possible thanks to Ductal® concrete.

6. #3
The Spinnaker Tower, in United Kingdom
The highest tower in England, the Spinnaker Tower rises 170 meters above sea
level in Portsmouth. It offers a panoramic view extending for 23 miles (37 km)
and boasts 3 different panoramic viewpoints.

7. #3
The Spinnaker Tower, in United Kingdom
The Spinnaker Tower, designed by Scott Wilson Advanced Technology Group,
was built in 2004 with Agilia® self-positioning, self-leveling concrete.

8. #4
The Rion-Antirion Bridge, in Greece
Built in 2004 by Gefyra, this bridge links the Peloponnesus with continental
Greece. With a length of 2,800 meters, it is the longest suspension bridge ever
built.

9. #4
The Rion-Antirion Bridge, in Greece
750,000 tons of high-performance aggregates were used to ensure the structure
is durable and extremely strong. The bridge can resist winds of up to 250 km/h, a
collision with an 180,000-ton oil tanker, or an earthquake of magnitude 7 on the
Richter scale.

10. #5
The Millau Viaduct, in France
Construction of the Millau Viaduct required most of the latest techniques used in
the civil engineering sector. Up until then (2004), no worksite had assembled
such a concentration of technologies in one place. The Viaduct is now the highest
cable-stayed bridge in the world.

11. #5
The Millau Viaduct, in France
With a maximum height of 340 meters, the Millau Viaduc is even higher than the
Eiffel Tower. 85,000 m³ (i.e. 206,000 t.) of concrete were used in the construction
of this concrete and metal marvel created by architect Norman Foster.

12. #6
Hypergreen, a tower concept for megalopolises
Hypergreen is a multi-function tower concept which respects the environment and
was developed for the world's megalopolises. The tower's geographic orientation
allows it to capture a maximum of light and wind energy. The tower is able to
generate enough energy to meet most of its own needs.

13. #6
Hypergreen, a tower concept for megalopolises
Developed by architect Jacques Ferrier in partnership with Lafarge, the tower
was designed around Agilia® self-positioning, self-leveling concrete and ultra-
high performance Ductal® concrete.

"Living infrastructure", a study of 4 inhabited bridges
In partnership with Lafarge, engineer-architect Marc Mimram proposes 4
innovative bridges suited to specific cities: the "Landscape Bridge" in La
Courneuve (France), the "Rooftop Bridge" in Shanghai (China), the
“Accommodating Structure" in New York (USA), and the "Inhabited Structure" in
Moscow (Russia).

"Living infrastructure", a study of 4 inhabited bridges
Generally poorly perceived, infrastructure is too often experienced as a
necessary evil in cities. In the context of this study, Ductal® ultra-high
performance concrete appears to be the ideal physical solution for creating the
engineer-architect's light and inventive forms.
