Abstract: A new and innovative approach to the material science has demonstrated that photocatalytic activity may be conferred to cementitious construction materials such as paints, mortars, concrete manufacts, pavements, etc.
This has been confirmed by the results obtained in the generalised use of self-cleaning surfaces which allows buildings to maintain their aesthetic appearance unaltered over time.
In parallel, the capability of photocatalysis in cementitious materials to reduce the levels of urban pollution has been demonstrated in laboratory, at pilot scale and, more recently, with some specific in-field monitoring programs carried in occasion of relevant realizations.
In this paper, after a description of the most relevant aspects concerning the photocatalysis applied to the cement-based materials, some test methods for the evaluation of the photocatalytic activity will be described. Furthermore, some pilot projects will be cited and finally, some examples of relevant applications will be reported.
