The Effect of TiO2 Nanomodifiers on Photocatalytic Activity and Mechanical Properties of Gypsum Plasters
The purpose of the research is to check the effect of adding photocatalytics nanomodifiers TiO2 on the physical and mechanical properties of gypsum plasters. It is shown that the use of nanosized titanium dioxide is one from ways of obtaining composite gypsum finishing plaster with improved mechanical and photocatalytic properties. The use of nano-sized doped titanium dioxide creates photocatalytic layer on the surface of the material that is activated by ultraviolet or visible light. With the help of nuclear power microscopy of microcracks and three-dimensional topography of the surface of gypsum plaster the presence of botryoidal agglomerates of titanium dioxide was established. The study of the macrostructure of the chips of gypsum binder compounds established that the pores of the composition with 2 wt.% TiO2/S,C contain agglomerates of doped nanocomposite, which compact the microstructure by filling the pores, which increase the mechanical properties of the material and reduce the possibility of cracking. Gypsum plaster, modified with nanomodifier TiO2/S,C, became 54% stronger than the control sample. When analyzing Raman spectra of gypsum plaster of additive-free composition and composition, modified 2 wt.% TiO2/S,C, it was established that the modified sample characterized by the presence of anatase titanium dioxide.
