Photo-catalytic Active Surface of Direct Finish Concrete on a Real Model of Self-supporting Porch

The paper describes verification of photo-catalytic properties of Titanium dioxide on the real model structure – a self-supporting porch made from photo-catalytic concrete with silicate surface treating. Individual parts were subjected to tests of humidity and spectrophotometric measurements of concrete with addition of TiO2 and silicate coating. All these properties have been and will be in long-term compared with the properties of an ordinary product without addition of TiO2. The model porch is now exposed to long-term action of weather and service influences in an agglomeration simulating industrial environment.
