TLuminous products are obtained from architectural and decorative concrete using photoluminescent pigment, formed in various positions and any configuration that does not lose their architectural expressiveness over a long period of operation. The use of products with a glow effect provides increased safety at night and is an additional means of signaling on dangerous and worst-lit sections of roads, parking lots, bicycle paths. Optimally selected materials and the method of surface treatment of products provide decorativeness of small architectural forms in the daytime. The compositions of architectural and decorative concrete are designed and the influence of the quantitative content of photoluminescent pigment on the main physico-mechanical characteristics is evaluated. The rheological properties of cement suspensions and architectural and decorative concrete based on them are studied, and the decorativeness and luminescence of products with photoluminescent pigment are evaluated according to the methods developed by the authors. The resulting recommended composition of glowing architectural and decorative concrete with using white Portland cement СEM I 52.5 N, fractionated marble crushing waste, modifier of polycarboxylate type and photoluminescent pigment, allows to obtain the products with a glow effect, high architectural, decorative and physico-mechanical characteristics.
