FIELD: chemistry.
SUBSTANCE: invention relates to structural materials and specifically to additives for concrete and mortar mixtures based on cement binder. The aggregate-plasticiser for cement binder-based mixtures contains the following components, wt %: finely ground limestone 60-98.8; polycarboxylate ester 1-10; lignosulphonate 0.005-10; 0.0005-5.
EFFECT: improved flow characteristics of the concrete and mortar mixture, high strength of hardened concrete and mortar (including at early hardening stages), low mortar- and water segregation of the concrete mixture, high water impermeability of the concrete, high frost resistance of the concrete, high sulphate resistance of the concrete.
