A recent study published by engineers from Oregon State University, Purdue University and Solidia Technologies shows potential in a new cement that gains strength from carbon rather than water. This cement react with carbon dioxide and calcium silicate rather than water.
While concrete made with this new cement may look like regular concrete, it has such benefits as better resistance to some of the most common de-icing salts. It could also reduce the carbon dioxide emission from the cement industry.
With this new cements roads could potentially be protected longer which will give them an economic advantage as well:
In places where deicing salts are routinely used, they can cause damage to roadways that cost about $1 million a mile to fix, and can reduce a 40-year lifespan of a surface to as little as 8-10 years," Weiss said. "By using a type of cement that requires carbon dioxide to make, and in turn greatly extend the lifespan of some roads, the environmental benefits could be enormous."
