The paper presents the results of experiments aimed to determine the effect of surfactants on the cementation rate and activation energy. The study was carried out on model solutions with the addition of surfactants. The results of the study showed that sodium lignosulfonate in a mixture with sodium dodecyl sulfate and sodium dodecylbenzene sulfonate increases the cementation rate over the entire range of studied concentrations. It is noted that the addition of individual surfactants leads to an increase in activation energy. Activation energy increases according to following order: sodium dodecylbenzene sulfonate → sodium dodecyl sulfate → sodium lignosulfonate.
