Abstract:
Paper deals with testing of surface photoactivity of fibre-cement composites. Self-cleaning ability, de-NO x activity, visual stability and weathering resistance were tested. Carriers of photoactivity were four different nanopowders with high content of anatase; crystalline form of TiO 2 . Photocatalytic properties of TiO 2 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 TiO 2 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-NO x process and decomposition of other gaseous pollutants. By this reaction the surface of composites containing large number of TiO 2 particles is able to maintain its original appearance by so called self-cleaning ability.
