Can a carbon tax save concrete!? 'Climate change may reduce concrete’s durability, with long-term consequences for buildings, roads and bridges constructed with the common material, according to a recent study.
Meet the authors of the 'study': Matthew Eckelman ([email protected]) and Mithun Saha of Northeastern University focused their research on how infrastructure in Boston will be affected by the most extreme climate change scenarios. They predict about 60 percent of Boston’s buildings will have some structural deterioration by 2050. Eckelman and Saha published their study results in the journal Urban Climate.
'Over time both carbon dioxide and chloride ions seep into the concrete and corrode the steel bars, called rebar. This corrosion expands the concrete, destabilizing it. Eventually, the damage becomes visible when the facade of a building cracks or chunks of concrete break off.'
