AbstractAbout AuthorsReferences
This paper is focused on gathering all available information on the application forms of photocatalytic TiO2 in concretes, especially in the surface layers of precast and monolithic structures. The paper describes in detail the properties of titanium dioxide alone and its special abilities leading to a substantial improvement of the environment through photocatalysis. Further verification methods of photocatalytic activity of titanium dioxide and titanium dioxide application in real projects are described.
