In accordance with the requirements imposed to binder materials for performing of modern constructions, a multitude of new materials with added value are researched and introduced in practice. The article presents both the obtaining method of photo-catalytic component (TiO₂ nano-structured), methods of photo-catalyst characterization and also the obtaining of photo-catalytic binder materials.  In order to obtain photo-catalyst material, the hydrothermal synthesis was used, and this material was characterized by X-rays diffraction in order to establish the composition and crystallites dimensions and by optical microscopy in order to see powders morphology. 

 Photo-catalytic binder materials with TiO₂ nano-structured were obtained. The own results obtained as consequence of characterization from physical-mechanical point of view (water for the slurry of normal consistency, setting time, stability, and also mechanical strengths at bending and compression) of these materials.
