The focus on sustainability continues to grow within the construction industry. Sustainability generally means having no net negative impact on the environment. Because concrete is the most widely used material worldwide, concrete industries have the environmental and societal responsibility to contribute to sustainable development. The concrete industry is a significant contributor to air pollution and also a consumer of vast quantities of natural materials, including water. It is general understanding that manufacturing 1 ton of Portland cement produces about 1 ton of CO2 and other greenhouse gases (GHG).
The concept of sustainable concrete (green concrete) construction is that the energy and resource consumption due to the construction and operation of a concrete structure must be minimised. To achieve this goal w.r.t sustainable concrete, this chapter describes in detail four parameters that need to be taken care of: minimise energy and CO2 footprint, minimise potable water use, minimise waste, and increase use of recycled content.
