ConcreteConcrete is the most used man-made material in the world with twice as much concrete used in construction than wood, steel, plastic and aluminum combined. Although concrete has acquired a negative image due to environmental impacts that occur at various stages of its production, sustainable use of concrete is possible by using alternative stablizers and construction techniques and restricting usage to certain building parts.

Given that the use of concrete is not likely to decline, it is important that more sustainable techniques of using concrete continue to be researched and promoted.
