Abstract: Photocatalytic cementitious building materials, mainly with incorporation of TiO2, have been
shown to be a promising remediation technique for air pollutants such as NOx and VOC’s,
frequently encountered in trafficked areas and the urban environment. In addition, this light-
induced phenomenon can be applied for self-cleaning and disinfecting surfaces (building
façades, decorative mortars, interior tiles, etc.). However, there are still doubts and questions
about the durability of the photocatalytic activities (for instance the air cleaning characteristic)
in time. 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”. This paper
presents first results of these investigations made independently in both countries, as a first
step towards the evaluation of the life time of these photo-active air purifying products.
