Smog getting you down? Never fear, self-cleaning concrete is here! Coated with titanium dioxide, the new concrete - called TX active - helps quicken the oxidation of harmful chemicals such as nitrogen oxides (smog contributors), carbon monoxide, and benzene (a carcinogen). For only a 30% premium over regular concrete, it can reduce NOx by up to 60%.
The producer envisions this concrete in urban environments such as sidewalks and streets, reducing car pollution and keeping the urban air cleaner. As a bonus, the active compound in the concrete keeps these substances from clinging to the concrete, making it look cleaner. Nice!
While this is no reason to keep working on pollution reduction through cleaner fuels and renewable, clean energy, it's nice to know we can help clean up the mess closer to the source.
