METHOD OF INTRODUCING PHOTOLUMINESCENT PIGMENTS IN PRODUCTS MADE OF DECORATIVE CONCRETE Russian patent published in 2018 - IPC B28B19/00 B28B1/87 B28B5/00 B28B11/24 

FIELD: construction.

SUBSTANCE: invention relates to the production of building materials and can be used to obtain a protective and decorative coating on the surface of building structures made on the basis of concrete, in particular paving slabs, curbs, as well as elements of decorative internal and external lining of walls of buildings and premises. Method of introducing pigments into decorative concrete products is that a pigment powder and a concrete mixture are prepared in advance in the product volume. At the same time, pigment powder is filled into the mold at a rate of 30–50 g per 1 m² of the mold surface, into which the concrete mixture is then laid and vibration of the mold with subsequent packaging of the formed product in a waterproof material is carried out with a holding time of at least 24 hours until the product completely cures. Photoluminescent pigment is used as a pigment.

EFFECT: technical result is an increase in the operational wear resistance of coatings with photoluminescent pigments.
