Abstract: Photocatalytic cementitious building materials, mainly with incorporation of TiO2 are being advertised as the promising technique to keep surface clean just thanks to illumination by light. This light-induced phenomenon can be applied for self-cleaning and disinfecting surfaces as building façades, decorative mortars, culture monuments etc. In addition, concentration of air pollutants such as NOx and VOC’s, frequently encountered in trafficked areas and the urban environment can also be reduced. However, there are still doubts and questions about the durability of the photocatalytic activities. To answer the logic question about the photocatalytic products service life, standardized testing methods have to be set up to give more reliable answers to the potential end users. First attempts have been made by Czech Republic and Belgian research groups within the European normalization efforts of CEN/TC386 “Photocatalysis”. The testing method based on several years’ studies incl. photocatalytic concrete manufactures was proposed for vertical as well as horizontal surfaces. This presentation presents examples of results of these investigations as the first step towards the evaluation of the life time of these photo-active air purifying products.
