Evaluating TiO2 and ZnO as photocatalytic additives in lime plaster for sustainable construction

The study investigates the efficacy of TiO2 and ZnO photocatalytic nanoparticle additives in lime plaster for sustainable construction. These additives could enhance the durability and self-cleaning capacity of lime plasters. While TiO2 is established as a photoactive additive, ZnO's potential remains unexplored. Our research evaluates their impact on pure lime plaster's physico-mechanical properties, proposing new standards for assessment. Our study, using analytical techniques including XRD, TGA and MIP, aims to promote the adoption of lime-based mortars with photocatalytic additives in eco-friendly construction.
