Tests on a road near Milan showed TX Active cut the level of nitrogen dioxide and carbon monoxide by as much as 65 percent. It functions via a chemical process called photocatalysis, whereby sunlight triggers a chemical reaction when titanium dioxide on the surface of the cement comes into contact with pollutants in the air. TX Active works most effectively in bright sunlight. Italcementi said test results have been verified by independent bodies like the National Research Council.

TX Active cement has already been used on a number of buildings, including Air France’s new headquarters at Paris’ Charles de Gaulle Airport, Rome’s Dives in Misericordia church and Bordeaux’s Hotel de Police.: 10897 De.
