In this article powdered composites of titanium dioxide and silica with high-developed surface(183–534 m2 / g), synthesized from industrial wastes, are considered as photocatalytic concrete additives. Their composition was studied, and the photocatalytic performance was evaluated by decomposition of the dye “Methylene blue” under UV-irradiation. The surfactant’s concentration at which the photocatalytic activity reaches its highest values was determined.
