FIELD: construction.
SUBSTANCE: superplasticising agent C-3, lignosulphonates, technological and sulfur-containing products - salts of desulfurisation of coke and by-products or sodium sulfate, or antichlor or their mixture are mixed at weight ratio of the mixture C-3 with lignosulphonates technological and sulfur-containing products (70-120):(5-30). Sulfur-containing agents are preliminary crushed in hammer grinder at centrifugal acceleration of 180-220 g reaching specific surface area 700-800 m2/kg, and superplasticising agent C-3 and technological lignosulphonates are mixed at weight ratio (20-30):(50-70) in a centrifuge at centrifugal acceleration of 1-3 g within 2.5-3.5 minutes and further powdered in roll crusher with inter - roll gap of 0.5-1.0 mm.
EFFECT: improved stability of the complex additive agent during storage, decreased consumption, prevention of efflorescence, enhanced early strength and frost resistance.
