Concrete is being recognized for its strong environmental benefits insupport of creative and effective sustainable development. In response togrowing environmental and economic forces, regulatories, engineers, developersand owners are seeking efficient, innovative concrete solutions that conservenon-renewable resources. When considering the lifetime environmental impact ofa building material -extraction, production, construction, operation,demolition and recycling- concrete is the most advantageous choice to meetthese goals. Globaldemands for regulating concrete production waste arise from the growth of theseenvironmental and economic issues. Various effortshave been conducted by researchers to arrive at some alternatives that are ableto significantly reduce high energy consumed and environmental impacts duringfabrication process of cement. Therefore, the concept of "green concrete"as an environmentally friendly alternative to conventional concrete has beenemerging. This publication seeks to demonstrate how concrete contributes tofuture generations’ sustainable development, and will be of interest toarchitects, engineers, policy makers, contractors and clients, as well asothers involved with the design, construction or operation of buildings andinfrastructure. The main objective of this study is to identify and evaluatethe key sources contributing to CO2 emissions from concrete and compare traditional concretes with “green concretes”, concretes producedwith blended cements and fly ash used as partial replacement of cement, inorder to diminish the environmental impact of the concrete production.
