FIELD: metallurgy.
SUBSTANCE: invention relates to foundry production. The mixture contains in wt %: modified aluminium-chrome-phosphate binding agent 2-6, hardening agent 0.1-3.0 and the rest of the mixture is a refractory filler based on silicon dioxide. Refractory composite "OSA-1" is used as a hardening agent.
EFFECT: high strength is stretched in 24 hours and reduced peeling of mixture compositions.
