FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Proposed suspension contains 26-31 wt % of electrolyte, refractory filler making the rest. 0.4-1.0%-water solution of carboxymethyl cellulose sodium salt flue ash is used as said electrolyte while thermal electric power station flue ash is used as refractory filler.
EFFECT: higher fireproofing properties and crack resistance.
