Compressive strengths reach up to 200MPa and flexural strengths reach up to 40MPa. Ductal ® covers a range of formulations that can be adapted to meet specific demands of different customer segments, enhancing the usage value and contributing to the overall construction performance. By utilizing the material's unique combination of superior properties, designs can eliminate passive reinforcing steel and experience reduced global construction costs, formworks, labour and maintenance; relating to benefits such as improved site construction safety, speed of construction, extended usage life and others.A number of references on Ductal ® already exist in different countries, both in structural and architectural segments. In this paper, the first use of Ductal ® for footbridges in France is presented. In Gorges de l'Herault, next to Montpellier, the 'Pont du Diable'Ductal ® footbridge, designed by the architect Rudy Ricciotti was constructed. This footbridge with a span of 68m was constructed by Freyssinet and Bonna Sabla. The transversal section is composed by two bone-shaped webs, with a height of 1,8m, connected by a light ribbed deck. Fifteen 4,6m length segments were prefabricated in a factory are delivered to jobsite. These elements were assembled by prestressing using 8 cables and then erected in one day.Read More
