WO2009013338A1
The present invention relates to new photocatalytic cement compositions, especially useful as paints, renders and plasters, provided with a high photocatalytic power and an optimal rheology, evaluated both in the step of preparing and in the step of applying The compositions according to the invention specifically consist of a combination of organic additives, which, mixed with water and.
Photocatalytic Efficiency of Cement-Based Materials
Therefore, the main objective is to propose a standard procedure for assessing the photocatalytic activity of cement mixtures with TiO2 additives and to define a parameter—the photocatalytic efficiency factor (PEF)—that could be used to compare the photocatalytic activity of different TiO2 cement mixtures, even for extended exposure conditions.
Photocatalytic Pavements
Sep 26, 2014· Abstract Pavements which have been blended, coated, sprayed, etc, with photocatalytic TiO 2 additives have attracted world-wide interest during the past decade-plus period based on their environmentally beneficial abilities to provide reactive (ie, ‘smog-eating pavement’ plus ‘self-cleaning’) and reflective (ie, ‘cool pavement’) impacts.

The photocatalytic additive allows to reduce the concentration of contaminants (NOx or VOCs), which are generated to a great extent by the intensity of traffic in large urban centers ADINS clean is suitable to be used in cement based materials, ceramics, glazes and coatings to obtain self-cleaning or decontaminant surfac FIELDS OF APPLICATION.
ADINS clean
ADINS clean is a functional additive based on a silicate doped with photocatalytic species which introduces in the host systems the capacity for removing organic matter from the surface by the action of light ADINS clean incorporates an innovative technology, which allows using lower dosages than photocatalytic based products, since ADINS clean is more active than any other photocatalitic.
