New recipe makes concrete that absorbs more CO2 than it emits
By A Mystery Man Writer
Description
Concrete is one of the most common materials on Earth, thanks to its high strength and low cost – but it’s also one of the largest single sources of carbon dioxide emissions. Engineers at Washington State University (WSU) have developed a new method for making concrete that absorbs more carbon than it emits.
