Concrete technology for a sustainable development in the 21st century focuses on the problems and challenges for the concrete industry today and in the future with particular emphasis on environmental consiousness. Primary topics include: the improvement of concretes service life to ease technical and economical problems and the waste of natural resources; environmentally friendly concrete production including new production methods and recycling materials; and actually using concrete to solve environmental problems, for example through the containment of hazardous waste.The book is the result of the international workshop held in Lofoton, Norway. With very select contributions from the most distinguished international professional experts, this book provides a basic framework and guidelines for national and international bodies.

Global Climatic Change (GCC) is changing the way we manage and maintain our concrete infrastructure. For the last 15 years CONSEC conferences have strived to bring experts on a common platform to discuss and disseminate international expertise with respect to performance of concrete under severe conditions. These conferences have closely followed the evolution of research in this area and have brought forward critical advances that are now been adopted worldwide. CONSEC’10 paid particular attention to new trends. Not only traditional themes, such as performance under severe environments and loading, concrete construction, codes and design, and maintenance and repairs, are included. Attention is also given to sustainability, high performance specialized materials, new NDT methods, and emerging fields such as structural health monitoring and sensing.The contributions in Concrete Under Severe Conditions show a clear accent on developing new technologies to reverse the trend in our decaying concrete infrastructure in both developed and emerging economies. This requirement has to be balanced with our need for sustainability, ecological preservation and environmental protection through the use of recycled materials and industrial by-products. Concrete Under Severe Conditions demonstrates the need for a continued dialogue and active cooperation between both developed and emerging economies to fully understand and deal with extreme environmental and loading issues on concrete infrastructure, and will be of interest to academics, engineers and professionals involved in concrete and concrete infrastructure.

Cement-based concrete has excellent properties as a construction material, and the raw materials of cement—rocks, and limestone and clay—are bountiful. Yet its production generates high quantities of CO2, making it a potentially unsustainable material. However, there are no alternatives to concrete and steel as basic methods for development of socioeconomic infrastructure at this time. Highlighting sustainability issues in the construction industry, The Sustainable Use of Concrete presents guidelines on how to move toward sustainable concrete construction.The book begins by clarifying the historic background and meaning of sustainability, after which it outlines areas that need to be considered in connection with sustainability in the concrete and construction field. It examines environmental, social and cultural, and economic aspects, then considers an evaluation system of sustainability. The authors include various tools and ISO standards, and then explore technologies for sustainability, with case studies and examples that promote understanding of current technologies. Although the construction sector, in the broadest sense, has come to recognize that infrastructure development over the past two centuries has been unsustainable, it has been slow to adjust. Comprehensive information and relevant practical guidance are very scarce. This book lays out a roadmap for creating a human-friendly and safe environment with low environmental burden.
