Abstract of the conference
Concrete remains the material of choice for the construction industry. Flexible and economical, it is used for a wide range of applications. This sustained interest for concrete has pushed engineers and researchers around the world to innovate. The introduction of new chemical admixtures and supplementary cementing materials has led to the development of a wide range of products, from high-performance concrete to self-leveling mixtures. To make sure that structures built with concrete would be safe and durable, numerous regulatory organizations have recently decided to develop a new generation of guide specifications centered on the expected performance of concrete. Pushed by a wide-range of stakeholders, performance specifications are now increasingly used in Canada, the United States and elsewhere around the world. A key point of this approach is that it often relies on numerical modeling to select the most durable solution. After a brief review of different guide specifications currently used around the world, typical design-build projects where performance specifications were used in conjunction with numerical modeling will be presented. Special emphasis will be put on the design and construction of the Third Set of Locks (the “new” Panama Canal).
