Abstract
Titanium dioxide (TiO2) is the most studied photocatalyst with application potential in many branches of industry. Building industry represent the sector, where the photoactive TiO2 have been already successfully utilized. Concretes, plasters, paints are building materials where the photoactive TiO2 is widely tested. However the amount of TiO2 in these materials is limited with respect to their final properties. If the TiO2 replaces the certain amount of cement in concretes, the resulting compressive strength decreases when this photocatalyst is added in non-adequate content. The surface of kaolinite particles can serve as a matrix for nanosized TiO2 growing what results in photoactive composite – kaolin/TiO2 formation. After the calcination of this composite the process of kaolinite dehydroxylation is responsible for metakaolinite formation and composite metakaolinite/TiO2 with latently hydraulic properties originates. If the metakoline/TiO2 is used for partial cement replacement the compressive strength of resulting samples is notably increased and its surface shows photodegradation ability against rhodamine B.
