✦ Synopsis

On the basis of the GPC method research has been done on the sorption of all components of ligninsulphonate additive and on the change of differential mass distribution of molar masses of additive after sorption on the surface of cements. Affinity of molecules of the sole ligninsulphonate fraction as well as of other components of additive /sorption capacity/ is influenced by the properties of cement. When the lowest concentration of additive in the suspension is used a selective sorption with more notable presence of fractions of the highest molar mass and the lowest presence of medium-molar fractions in the sorbed fraction of the additive occurs.
