New Findings On Concrete Absorption Of CO_2

摘要

Despite The fact that many scientists believe that the concrete industry is responsible for 5 percent or more of the world's carbon dioxide (CO_2) emissions, several well-known studies have shown that concrete is able to reab-sorb small quantities of CO_2, effectively lowering its overall carbon "footprint." While it has been known for some time that this reabsorption can occur over the course of decades as concrete, which is permeable, combines with CO_2 to form the mineral known as calcite, new research suggests that the reabsorption of CO_2 might extend to the formation of additional products as well.
