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 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 concrete which is constructed which minimizes the environmental impact through its life cycle, Concrete is considered sustainable material. It has low inherent energy requirements, it’s produced to order with little waste, it’s made from plentiful resources and can be made with recycled materials and recycled crushed aggregates, and it is recyclable itself. Many recycled materials that can be used in concrete, starting from recycled water and recycled aggregates and recycled by-product materials can be implemented in many different concrete structure applications
