FIELD: powder metallurgy, building materials, particularly, gas-generating compounds applicable in production of cellular concrete, cellurization of other inorganic mixtures, and aqueous aluminum pigments applicable in paint and varnish industry. SUBSTANCE: aqueous aluminum paste contains aluminum powder with specific surface from 10 to 25 thou.sq.cm/g and aqueous solution including corrosion inhibitor, wetting agents and stabilizers with the following amounts of components, wt.%: aluminum powder 50-70; wetting agent 0.5-1.0; inhibitor of aluminum corrosion-hydrolyzer 0.5-2.0; stabilizer-thickener 0.5- 2.0; the balance, water. Wetting agent is used in form of oxyethylated alkyl phenol OP-7 or OP-10. Inhibitor of aluminum corrosion-hydrophylizer is in form of potassium, sodium, ammonium salts of chromic acid, and/or organic substances from the following series: sulfonol, sulfite liquor, lignosulfonates, and stabilizer-thickener is used in form of colloids from series: carboxymethyl cellulose, gum arabic, gelatin, starch. EFFECT: higher stability of quality of aqueous paste in storage and under effect of seasonal temperature fluctuations. 4 cl, 1 tbl
