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. ^ 1 tbl |
