Testing of surface photoactivity of fibre-cement composites

Popis výsledku v původním jazyce

Paper deals with testing of surface photoactivity of fibre-cement composites. Self-cleaning ability, de-NOx activity, visual stability and weathering resistance were tested. Carriers of photoactivity were four different nano-powders with high content of anatase; crystalline form of TiO2. Photocatalytic properties of TiO2 particles are maintained even after mixing with cement in composite matrix. Natural photolysis as reaction of material and UV light is accelerated in presence of a proper form of TiO2 as a catalyst which by producing free radicals is able to oxidize organic matter and even small inorganic particles. Oxidized material is mostly less harmful considering the de-NOx process and decomposition of other gaseous pollutants. By this reaction the surface of composites containing large number of TiO2 particles is able to maintain its original appearance by so called self-cleaning ability.
