As a crucial element in construction, tunnels, roads, pavements, and more, concrete has become one of the most important materials in the world. At the same time, air pollution, particularly in crowded cities, is increasing, mainly due to industrial activity and transportation. Therefore, one possible approach to fighting pollution is the use of “smart” construction materials, particularly the incorporation of photocatalytically active nano- and micro structures into concrete. Incorporating titanium dioxide (TiO2) in roads and pavements could degrade and, as a result, reduce various pollutants under ultraviolet radiation. The TiO2-infused concrete would also maintain its optical characteristics for far longer than traditional concrete mix. This research presents an evaluation of nano- and micro-TiO2-incorporated concretion degradation of organi.. View More»
