Progress of functionalized TiO2-based nanomaterials in the construction industry: A comprehensive review

Abstract The intensive development of construction in recent years and the increasing demands on the durability and service life of buildings have increasingly made the construction industry pay attention to new materials solutions based on nanotechnology. One of such solutions is the use of titanium dioxide with photocatalytic and antibacterial properties in building materials. Although this solution has been known for decades, there are few articles that review the latest trends in this area. Compared to other literature studies, this article pays particular attention to the possibility of modifying nanotitania to expand its photocatalytic properties and analyses the effects of these alterations on the self-cleaning, smog-abating and antibacterial properties of building materials, mainly cement-based composites. It is complemented by a section dedicated to the mechanical and durability properties of pristine and functionalized TiO2-modified building materials, taking into account dispersion methods, rheological and mechanical parameters as well as resistance to external factors.
