The 5th international Conference on Concrete under Severe Conditions of Environment and Loading (CONSEC’07) will be held in Tours, France, from June 4-6, 2007.
The objective of the CONSEC Conferences is to focus on concrete infrastructures, either subjected to severe environment or severe loading, or any combination of severe conditions. Experience from the performance of existing concrete structures, and especially under severe environmental conditions, severe accidental loading or extended lifespan, has demonstrated the need for better integration of structural and durability design, new design concepts including reliability-based durability design, performance-based material requirements, and an improved basis for documentation of obtained construction quality and durability properties during concrete construction. An improved basis for operation and preventive maintenance of concrete structures including repairs and retrofitting is also very important.
Premature corrosion of reinforcing steel, inadequate structural design for seismic or blast loading, are examples of reduced service life of concrete structures that not only represent technical and economical problems, but also a huge waste of natural resources and hence also, an environmental and ecological problem. Experience of structures effectively submitted to severe conditions represents a unique benchmark for quantifying the actual safety and durability margin of concrete structures. In fact for several reasons, most concrete design codes, job specifications and other requirements for concrete structures have frequently shown to yield insufficient and unsatisfactory results and ability to solve the above problems, as well as issues raised by specific very long-term or very severe requirements for nuclear and industrial waste management, or civil works of strategic relevance. Recently available high to ultra-high performance concrete may find rational and valuable application in such cases. It is very important, therefore, to bring people with different professional backgrounds together to exchange experience and develop multi-disciplinary ideas in order to improve the current situation.
The previous CONSEC conferences were held in Sapporo, Japan (1995) ; Tromsø, Norway (1998) ; Vancouver, Canada (2001), and Seoul, South Korea (2004). The exchange of information included detailed survey of existing structures, well-designed laboratory tests, case analyses using durability mechanics and refined concrete modeling, presentations of (ultra)-high performance concrete solutions for projects with (ultra)-severe environments, loadings or long lifespan, and proposals for new design concepts and codes. From these conferences which were highly successful events with about 300 participants from up to 37 countries, the peer-reviewed papers have been published in a series of Proceedings with significant archival value.
