Materiali cementizi fotocatalitici per il rivestimento superficiale di edifici
Innovative cement-based pre-mix products developing photocatalytic activity for surface coating of buildings is a particularly interesting way to improve environmental conditions in urban centres. These products are particularly suited to be used in the historical centres of cities, where, by necessity tied to the movement of people and goods, it is not possible to close the streets to vehicular traffic, so determining a substantially condition of air pollution. The study describes some pre-mix products, containing mineral pigments, the assessment of their photocatalytic activity, using a well-established testing method and shows how the results are influenced by different aging conditions …
Photocatalytic properties of cement-based plasters and paints, containing mineral pigments
Innovative cement-based pre-mix products, for surface coating of buildings, possessing photocatalytic activity, arouse great interest due to achievable results in terms of reduction of the air pollution and in the maintenance of aesthetics.The photoactivity is induced by the presence of a photocatalyst, titanium dioxide, which can accelerate the oxidation processes of air pollutants, particularly nitrogen oxides (NOx) and volatile organic compounds (VOCs), mainly produced by incomplete combustion of fuel and present in urban environment through the exhaust gases of motor vehicles. The surfaces which are coated with these products acquire a self-cleaning characteristic (maintenance of origin…
Experimental evaluation of the durability of innovative cementitious coatings: photocatalytic activity and colour
Today, in a world context characterized by high pollution levels and increasingly limited natural resources, even in the building sector, focusing on environmental issues, through energy saving and a more rational use of these resources, both during construction and management, is fundamental. An important contribution in this direction is given by the knowledge of the durability of products and building components, especially when innovative products are applied and no information are available on the reliability and service life. The research concerns the evaluation of the durability of cement-based photocatalytic coatings ("rasanti" in the Italian diction), containing different types of …
