Abstract
This paper addresses the evaluation of the photocatalytic properties of concrete containing titanium dioxide (TiO2). Here, the assessment of the air purifying abilities of the hardened concrete regarding the degradation of nitric oxide (NO) is of major interest. A setup for measuring the performance of these photocatalytic active concrete products will be presented. The test setup uses the UV-A induced degradation of NO and is oriented on the draft version of the ISO standard TC 206/SC N [1]. By means of this test setup, the influence of boundary conditions like irradiance, relative humidity, surface texture, flow rate and pollutant concentration on the degradation mechanism is investigated and a suitable measuring procedure is suggested for evaluating the performance of concrete products having photocatalytic activity. The suggested measuring procedure is used for the analysis of own developed mortar mixtures and a comparative analysis of already available concrete products on the European
market.
