FIELD: construction.
SUBSTANCE: method includes the use of surface-active substances in producing concrete. The surface-active substances are produced by sulfurization of heavy secondary products of pyrolysis of hydrocarbons with the boiling temperature above 170oC in the presence of an addition and further neutralization of sulfonated material.
EFFECT: improved plasticity and concrete strength.
