New mix could double concrete’s carbon uptake

Cement, a component of concrete, produces 8% of the world’s carbon footprint. Looking to lower that percentage, Purdue University engineers have discovered a way to make concrete more sustainable. Their new recipe for concrete has the potential to cut carbon emissions dramatically, creating building blocks for a better world. A team lead by Mirian Velay-Lizancos, an assistant professor of civil engineering at Purdue, proposes adding small amounts of nanoscale titanium dioxide to the cement paste that makes up concrete. They found that titanium dioxide, a powdery substance known best for its uses in sunscreen, paints, plastics, and food preservatives, enhances concrete’s natural ability to sequester carbon dioxide. The team discovered that adding only small of nano-titanium dioxide nearly doubles concrete’s absorption of the problematic greenhouse gas. Their study recently appeared in the scientific journal Construction and Building Materials.
