It is known that the efficient kinds of photocatalytic additives for cement materials are “core–shell” compositions synthesized by precipitation of photocatalyst particles on mineral substrates (dispersed carriers). The study aim was to install patterns of influence of 5 mineral modifiers on the technological characteristics of cement systems with finding of the most promising raw materials for dispersed carriers of photocatalytic agents. The increased technological efficiency of silica fume, metakaolin and expanding sulfoaluminate modifier in cement paste, due to the peculiarities of their granulometric composition with high dispersity and defectiveness of particles, was revealed by the research results. It predetermines the prospects of using these mineral additives in the composition of photocatalytically active self-cleaning cement materials.
