Production of novel eco-composite nano-mortars for architectural finishing, designed to combat environmental pollution affecting building shells, is reported. Specimens consist of a natural hydraulic lime mortar matrix doped with various kinds of nano-photocatalysts, produced from valorized industrial wastes: TiO2-hexaferrite from Fe3O2, and Ti(SO4)2-hydroxyapatite from Atlantic codfish bones. Samples were characterized and their photocatalytic activity was evaluated. Analysis showed that industrial wastes may be usefully reused to produce a new generation of sustainable, cheap and multifunctional novel building materials.

Abstract
Production of novel eco-composite nano-mortars for architectural finishing, designed to combat environmental pollution affecting building shells, is reported. Specimens consist of a natural hydraulic lime mortar matrix doped with various kinds of nano-photocatalysts, produced from valorized industrial wastes: TiO2-hexaferrite from Fe3O2, and Ti(SO4)2-hydroxyapatite from Atlantic codfish bones. Samples were characterized and their photocatalytic activity was evaluated. Analysis showed that industrial wastes may be usefully reused to produce a new generation of sustainable, cheap and multifunctional novel building materials.
