Proceedings pro066 : 2nd RILEM International Workshop on Concrete Durability and Service Life Planning - ConcreteLife'09
Title: 2nd RILEM International Workshop on Concrete Durability and Service Life Planning - ConcreteLife'09 Edited by K. Kovler ISBN: 978-2-35158-074-5 e-ISBN: 978-2-35158-085-1 Pages: 626 Publication date: 2009 |
The 2nd International RILEM Workshop on Concrete Durability and Service Life Planning 'ConcreteLife’09' is organized under the scientific sponsorship of the International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM), in conjunction with the 63rd RILEM Week. It was preceded by 'ConcreteLife'06', which was co-sponsored by RILEM and Japan Concrete Institute (JCI) and took place in the Dead Sea, Israel, in March 2006.
'ConcreteLife’09' is held at the Technion - Israel Institute of Technology, Haifa, at the facilities of the Faculty of Civil and Environmental Engineering and the National Building Research Institute.
The object of 'ConcreteLife’09' is to discuss the future trends in research, development, and practical engineering applications related to durable concrete construction. A focus of the workshop will be the design and construction of concrete structures exposed to different environmental conditions and mechanical loading. Although reinforced concrete structures can be designed and built to be durable in harsh conditions, there are numerous occasions where this potential is not materialized.
The economic implications of the damage when such deterioration occurs are quite large. For example, the annual cost of repairs of concrete and reinforced concrete structures deteriorated due to chloride corrosion only in the Middle East, Far East, North Europe and North America, is estimated to be hundreds of billions of dollars. Therefore, the problem of durable concrete materials and life-cycle evaluation of concrete structures for use under severe environmental conditions and mechanical loading is crucial.
The research cooperation in studying the processes of concrete deterioration in different conditions, and the development of advanced high-performance materials, with a focus on utilization of industrial by-products, such as coal fly ash and granulated slag, is expected to bring scientific and practical benefits for the society.
The 2nd International RILEM Workshop on Concrete Durability and Service Life Planning 'ConcreteLife’09' is intended to bring together international experts dealing with this variety of topics as a step for synthesis of the different complementing approaches to the issue of durability and service life planning of concrete structures.
