FIELD: manufacture of building materials.
SUBSTANCE: invention is directed to preparation of plasters, finishing compositions, and concretes. Complex additive for cement binder, containing saponified wood resin (0.5-2%), superplasticizer S-3 (15-21%), and finely divided filler (55-70%), is characterized by that finely divided filler is ground aleurite and that additive further contains polyethylhydroxysilane (0.05-0.075%), carbon black as hydrophobization agent (0.1-0.25%), and potassium carbonate as curing agent (14-25%).
EFFECT: increased frost resistance and corrosion resistance and also speeded up strength development in early solidification phase.
