This is not news, I am not in the field and have known it for ages. So have cement makers that make specialized cement. The immediate money will be in making a special liquid that can be sprayed in existing concrete building to make them last longer. If I'm building a 100 story tower in NYC, why spend, say x% more, when the building is likely to be sold 20 times in those 100 years? Now if I'm a state government with crumbling bridges, I'm extremely interested to make them last another 10-100 years. They are many companies already like Penetron that have special solutions to stop water penetration. MIT, IIRC, figured out how to stop the chemical reaction in concrete, making it last a theoretical 16,000 years. http://web.mit.edu/newsoffice/2009/creep-0615.html http://web.mit.edu/newsoffice/2009/creep-0615.html
