The Nano Secret to Concrete. Researchers aim to cut carbon-dioxide emissions by shedding light on the nanostructure of cement.

Concrete is the most widely used man-made material, and the manufacture of cement–the main ingredient of concrete–accounts for 5 to 10 percent of all anthropogenic emissions of carbon dioxide, a leading greenhouse gas involved in global warming. But now, researchers at MIT studying the nanostructure of concrete have made a discovery that could lead to lower carbon-dioxide emissions during cement production.
