FIELD: construction; chemistry.
SUBSTANCE: invention relates to the industry of construction materials, specifically to decorative concrete, and can be used in making architectural concretes ("arch-concretes") for making small-piece articles of any shape, which are used for decorative purposes. Architectural concrete is obtained from a mixture containing, wt.%: quartz sand 28.96–29.15, black crushed stone with fraction 2–5 mm or fraction 5–20 mm 36.45–36.67, binder is industrial wastes 24.3–24.45, alkaline binder activator 6.08–9.33, black iron oxide pigment 0.81, water is the rest.
EFFECT: obtaining architectural concrete of black colour, having a colour depth of 2% of reflected light, with low consumption of pigment, recycling industrial wastes.
