FIELD: chemistry.
SUBSTANCE: invention relates to construction materials, and more specifically to compositions of complex additives, used in making concretes, mortars, reinforced concrete and special concrete products. The complex additive contains a mixture of ballast salts from desulphurisation of coke gas based on sodium thiosulphate and rhodanate in amount of 30-65 pts. wt and product of neutralisation of distillation residue from production of acrylic acid in amount of 35-70 pts. wt.
EFFECT: improved fluidity of concrete, density of concrete and faster strength gain, as well as reduced input of additive.
