Abstract :

In recent years, environmental concerns of pollution and resource depletion represent major concerns for society. Air quality in the vicinity of large cities is linked with serious health hazards. Many of these health hazards are associated with nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the air, which in turn are caused by high traffic volumes and combustors. These pollutants may also travel long distances to produce secondary pollutants, such as acid rain or ozone (Beeldens 2006).The product TX Active (Titanium dioxide used as catalyst), is a patented portland cement developed by Italcementi Group and produced in North America by its U.S. subsidiary, Essroc. The key to TX Active’s properties are photocatalytic components that use the energy from ultraviolet rays to oxidize most organic and some inorganic compounds. Air pollutants that would normally result in discoloration of exposed surfaces are removed from the atmosphere by the components, and their residues are washed off by rain. So, this new cement can be used to produce concrete and plaster products that save on maintenance costs while they ensure a cleaner environment.This paper presents an overview of the principle of photo catalysis and the application in combination with cement, as well as the results of the laboratory research especially towards air purifying action.  The implementation of this type of material in urban and interurban areas is not only ecofriendly but also a great savage for society.
