The scope of the study is to test the influence of nano-TiO2 and ETS biocide addition on the mechanical and fungicidal properties of cement mortars. It is shown that the use of doped titanium dioxide and thiosulphanate structure modifier of the antifungal agent ETS is one of the ways to obtain an effective composite antifungal additive to cement mortars. The possibility of developing such complex additives to achieve a synergistic effect in the field of fungicidal coatings has been investigated. The use of nanosized doped titanium dioxide creates a photocatalytic layer on the surface of the material, which is activated by UV or visible light, while the biocide ETS modifier works in the dark, also extending the spectrum of action to other living organisms. Modified with such an additive, cement mortar became 19% stronger than the control sample. The change of the surface microstructure, the appearance of a significant number of mesopores and macropores, which creates a larger surface, thus increasing the photocatalytic activity, was confirmed. A comparison of the growth of mold colonies on control and modified samples is shown.
