FIELD: chemistry.
SUBSTANCE: invention relates to a carbon nanocluster sulpho-adduct which is the polar solvent soluble fraction of the product of a reaction between ground coal-tar pitch and sulphuric acid, followed by washing the unreacted acid with water. The obtained product can be used for low-temperature carbonisation when filling porous bodies and modifying carbon fibres and fabric and as a concrete plasticiser modifier.
EFFECT: improved plasticising and water-reducing properties, powerful antiviral properties.
