“…Цементные материалы, в частности бетоны, являются самыми распространенными материалами в строительстве, а их производство наиболее крупнотоннажным в своей отрасли. Приоритетным направлением в строительной индустрии является создание строительных композитов с новыми свойствами [1][2][3][4]. В связи с этим, применение бетонных изделий в качестве носителей фотокатализаторов, с целью снижения концентрации загрязняющих веществ в атмосфере является целесообразным и обоснованным.…”

The paper reviews the available technologies for producing photocatalytic active self-cleaning materials based on cement, including concretes and dry building mixtures. Used photocatalytic additives and their influence on the cement system are considered. The applied methods for assessing the photocatalytic activity of self-cleaning cement materials are presented. The compositions of concrete mixtures, their properties, areas and prospects of application are analyzed. The main problems of development, production and application of photocatalytic active self-cleaning materials based on cement are presented. The main directions to increase the self-cleaning ability of photocatalytic active materials based on cement are: optimization of the microstructure of the photocatalyst and the composite with its use in the direction of creating a developed surface of the photocatalyst - hierarchical microstructure; it intensifies the diffusion processes of photocatalytic reaction reagents and increases the contact area photocatalyst with a pollutant; it absorbs and accumulates ultraviolet radiation waves; optimization of the phase composition of titanium dioxide - search for the ratio of the anatase and rutile phases, at which the maximum photocatalytic activity is achieved; choosing of economically feasible method for periodical updating of the surface of concrete products carbonized during operation in order to restore self-cleaning ability.
