ABSTRACT
Climate change is anticipated to have a major impact on concrete structures through increasing rates of deterioration as well the impacts of extreme weather events. The deterioration can affect directly or indirectly the climate change in addition to variation in carbon dioxide concentration, temperature, and relative humidity. The deterioration that occurs from the very beginning of the service not only reduces the lifespan of the concrete, but also demands more cement to maintain its durability. Meanwhile, the repair process of the damaged parts is highly labor intensive and expensive. Thus, the self-healing of such damages is essential for the environmental safety and energy cost savings. The design and production of both self-healing and sustainable concretes are intensely researched within the construction industry. In this chapter, the cement-generated environmental problems, concrete performance in aggressive environment, and cracks and deterioration cases are reviewed. The sustainability of smart cementitious materials, effects of addition self-healing agents on concrete properties and life cycle assessment of smart concrete are discussed and analyzed.
