Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of a significant amount of carbon dioxide, a greenhouse gas. It also leads to depletion of aggregate and water resources.
Environmental issues are playing an important role in the sustainable development of the cement and concrete industry. A sustainable concrete structure or infrastructure is constructed to minimize the environmental impact through its life cycle. Concrete is considered a sustainable material. It has low inherent energy requirements; it is produced with little waste and from plentiful resources; it can be made with recycled materials and recycled crushed aggregates; and it is recyclable itself. Many recycled materials used in concrete – from recycled water, recycled aggregates, and recycled by-product materials – can be implemented in many different concrete structures.
