Abrégé

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 other components, provides cement compositions significantly more effective than the known compositions, both as far as rheology and photocatalytic power are concerned. The cement composition thus obtained associate features which have hardly been compatible up to now: on one side, a good workability (therefore a low viscosity) upon preparation from dry mixtures; on the other side, a good consistency in a wet state just after application. This avoids the occurrence of undesirable dripping before consolidation of the product. Finally, the photocatalytic power results surprisingly higher with respect to that of the known reference compositions when the same photocatalyst is used.
