摘要

Polymeric concrete performance in polluted environment has been studied in order to determine outdoor pollutant transfer process. SO_2 oxidation process over different building materials in laboratory-based atmospheric flow chambers is well known; however, the effect of NO_x is not very clear. In order to clarify this process, the effect of NO_x in SO_2 oxidation over the surface of a porcelain material was studied under wetted and unwetted conditions. In the chamber, NO_x can either catalyse SO_2 reaction or undergo oxidation to NO_3~-. The main conclusion in this work is that for the porcelain samples under wetted conditions NO and NO_2 catalysed the reaction. But in unwetted conditions NO reacts with the sample instead of SO_2.
