FIELD: construction.

SUBSTANCE: invention relates to a dry construction mixture containing, as a hydraulic binder, a derivative of calcium aluminosilicate activated by a side product of industry. The dry construction mixture contains: a hydraulic binder, granulates and/or finely ground limestone or siliceous fillers, at least one base at the following ratio of components of the dry construction mixture, wt.%: hydraulic binder – 5-70, granulates – 20-95; the specified finely ground fillers – 0-30; and the base in the amount less than or equal to 0.5% of the total weight of the dry construction mixture. In this case, the hydraulic binder contains at least one derivative of calcium aluminosilicate in the amount of 5-60 wt.% of the weight of the dry construction mixture, at least one ground granulated slag with a high content of aluminum oxide, containing 30-60 wt.% of aluminum oxide and less than 30 wt.% of silicon dioxide, wherein the specified slag with a high content of aluminum oxide is slag, in which aluminum oxide is the most common component, while the specified slag is used in the amount of 0.1-5 wt.% of the total weight of the dry construction mixture, and at least one source of calcium sulfate in the amount of 0.5-4 wt.% of the total weight of the dry construction mixture. A method for producing a wet construction mixture is also described.

EFFECT: production of a construction mixture.
