Concrete That Cleans Air
Hmmm... concrete that eats pollution. That's pretty slick if you ask me.
The results so far are astonishing: A street in the town of Segrate, near Milan, with an average traffic of 1,000 cars per hour, has been repaved with the compound, "and we have measured a reduction in nitric oxides of around 60%," says Italcementi's spokesperson Alberto Ghisalberti. In a test over an 8,000 square meter (or approximately 2 acres) industrial area paved with active blocks near Bergamo, Italcementi's hometown, the reduction was measured at 45%.
In large cities such as Milan, with persistent pollution problems caused by car emissions, smoke from heating systems, and industrial activities, both the company and outside experts estimate that covering 15% of all visible urban surfaces (painting the walls, repaving the roads) with products containing TX Active could abate pollution by up to 50%, depending on the specific atmospheric conditions.

I'm a boy... from San Diego, CA (USA). And I don't really have a whole lot else to say about myself.
