The France Pavilion at 2010 World Expo, in China

Conceived and designed by architect Jacques Ferrier, the Pavilion is a symbol ofinnovative French engineering. Outside the Pavilion, this expertise is illustratedby a concrete mesh - a symbol of power and refinement, encircling it andappearing 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 isdedicated to touch. Made from Ductal® concrete, it is decorated with numeroussmall multi-colored squares combining photos and samples of decorativeconcrete.

The Peace Footbridge, in South Korea

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

The Peace Footbridge, in South Korea

"This footbridge has a span of 130 meters but the deck (horizontal platform) isonly 3 cm thick!" architect Rudy Ricciotti points out. This exceptional feat wasmade possible thanks to Ductal® concrete.

The Spinnaker Tower, in United Kingdom

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

The Rion-Antirion Bridge, in Greece

Built in 2004 by Gefyra, this bridge links the Peloponnesus with continentalGreece. With a length of 2,800 meters, it is the longest suspension bridge ever

built.

The Rion-Antirion Bridge, in Greece

750,000 tons of high-performance aggregates were used to ensure the structureis durable and extremely strong. The bridge can resist winds of up to 250 km/h, acollision with an 180,000-ton oil tanker, or an earthquake of magnitude 7 on theRichter scale.

The Millau Viaduct, in France

Construction of the Millau Viaduct required most of the latest techniques used inthe civil engineering sector. Up until then (2004), no worksite had assembledsuch a concentration of technologies in one place. The Viaduct is now the highestcable-stayed bridge in the world.

The Millau Viaduct, in France

With a maximum height of 340 meters, the Millau Viaduc is even higher than theEiffel Tower. 85,000 m³ (i.e. 206,000 t.) of concrete were used in the constructionof this concrete and metal marvel created by architect Norman Foster.

Hypergreen, a tower concept for megalopolises

Hypergreen is a multi-function tower concept which respects the environment andwas developed for the world's megalopolises. The tower's geographic orientationallows it to capture a maximum of light and wind energy. The tower is able togenerate enough energy to meet most of its own needs.

Hypergreen, a tower concept for megalopolises

Developed by architect Jacques Ferrier in partnership with Lafarge, the towerwas 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 4innovative bridges suited to specific cities: the "Landscape Bridge" in LaCourneuve (France), the "Rooftop Bridge" in Shanghai (China), the“Accommodating Structure" in New York (USA), and the "Inhabited Structure" inMoscow (Russia).

"Living infrastructure", a study of 4 inhabited bridges

Generally poorly perceived, infrastructure is too often experienced as anecessary evil in cities. In the context of this study, Ductal® ultra-highperformance concrete appears to be the ideal physical solution for creating theengineer-architect's light and inventive forms.
