FIELD: production of additives for concrete mixture. SUBSTANCE: aqueous solution of technical lignosulfonate and waste aqueous solution of sulfurous purification of coke-chemistry plants on the base of sodium thiosulfate are mixed. Then drying and two-stepped granulation are carried out. Quantity of granules having 1-5 mm in size is 65-73 %, quantity of granules less than 1 mm in size is 5-25 %, quantity of granules more than 5 mm in size is 2-25 %. EFFECT: improved efficiency.
