Abstract
There is described a cement composition, based on hydraulic binders, adapted to obtain coatings with a high photocatalytic activity and improved rheologic characteristics, including a hydraulic binder, a polycarboxylic or acrylic superfluidifying agent, a cellulosic ether with a viscosity in the range between 10000 and 120000 mPa·s, an adhesive agent, a calcareous, silicic or silicic-calcareous filler and a photocatalyst.
