Abstract

The present invention relates to a photocatalytic concrete product and a method to produce a photocatalytic concrete product. In first aspect the invention relates to method of producing photocatalytic concrete product, said concrete product being photocatalytic by containing nano sized photocatalytic particles embedded in an section including a first surface, said first surface forming an exterior surface when the photocatalytic concrete product is used as cover/lining. The method comprises: providing a not-yet-set concrete product having a first surface, applying a dispersion containing nano sized photocatalytic particles, such as titanium dioxide nanoparticles a solvent including a humectant onto said first surface of the not-yet-set concrete product.
