FIELD: construction.
SUBSTANCE: in the method for production of a magnesia binder - brucite is ground, burnt and milled into a powder, besides, the specified raw materials are ground to the fraction of 0-0.5 mm, then mixed with the technical lignosulfonate binder in the amount of 3-4% of brucite weight, sealed with water with bischofite dissolved in it in the amount of 3-5% of brucite weight, granules are formed and baked at the temperature of 800-850°C for 1.5-2 hours, cooled and ground until residue on a sieve of 0.08 is not more than 15%.
EFFECT: higher strength and evenness of volume variation with simultaneous reduction of baking temperature.
