The problem with reinforced concrete (2016)
This should be an economics piece, not an environmental piece.
The author states that "one of iron’s unalterable properties is that it rusts" yet further on acknowledges the existence of stainless steel.There's nothing wrong with reinforced concrete, but the incentives to produce long lasting buildings are not there. The cheapest bidder will generally win and their building will last the "design life" of the building, but often not much more. The simplest way to change this is to extend the design life, which would result in stainless steels or another more expensive material being used in this application.
