This paper is devoted to the development of nano-modified cementing composites in the field of self-cleaning building materials. Particle-size distributions of the main constituents such as ultra-fine zeolite and limestone of multicomponent cements, and titanium dioxide and kaolin additives are given. The degree of the interphase of the active surface in Portland cement and supplementary cementitious materials is calculated. It has been shown that due to the synergistic effect, anatase and rutile mixtures can be included in cementing composites to improve the properties of self-cleaning plasters. The influence of titanium dioxide and kaolin additives on the mechanical properties of nano-modified multicomponent cement was investigated using the method of mathematical planning for the experiment. The results obtained using the XRD and SEM methods showed that the addition of high-surface-area nano-scale particles of TiO₂ to the cement paste leads to the formation of a denser microstructure in the cementing matrix.
