FIELD: construction.
SUBSTANCE: complex admixture for concrete mix contains Giperlit hyperplasticising agent and Taunit carbon nanostructured material (CNM) at the following component ratio, wt %: Giperlit hyperplasticising agent - 99.5-99.7, Taunit carbon nanostructured material - 0.3-0.5. A preparation method of the proposed complex admixture consists in ultrasonic dispergation of Taunit carbon nanostructured material in Giperlit hyperplasticising agent during 3-7 minutes by means of UZG13-0.1/22 ultrasonic generator.
EFFECT: increasing growth rate of strength of concretes at early hardening stage at preservation of their high final strength; increasing freeze resistance and water non-permeability.
