Concrete and sustainability In view of the development of world concrete and construction we see an evolution of the focus in the direction of: Safety Durability Serviceability Functionality Sustainability It is important in this context to learn at least two things: All the focuses in the evolution process are closely linked to each other and function upon need instead of occurring and existing independently or replacing one by another. The latest developed focus Sustainability is not only evolved from the previous focuses but works as a function of them as well. We therefore believe that sustainability is not only an environmental performance it is indeed a holistic thinking approach that can be considered as the function of safety durability functionality and economical feasibility environmental compatibility and social responsibility. The level magnitude of each focus to sustainability varies depending on the specific requirement of the target and local boundary conditions
