Abstract

The creation of stable disperse systems and cement slurries with regulated rheological properties is a very urgent problem for national economy of every country. To effectively solve these problems, it is necessary to widely use high effective stabilizing and plasticizing surfactants for disperse systems and cement mixtures. The aim of the work was to study colloid-chemical properties and efficiency of new surface-active derivatives of benzoic acid for disperse systems equilibration. Different methods for the measurements of properties and efficiency of new surfactants were used. The effects of concentration and temperature on the surface-activity and foaming abilities of new surface-active derivatives of benzoic acid were studied. It was established that with an increase in the concentration of surfactants and the length of the hydrocarbon chain in the surfactant molecule, the surface activity and foaming ability of benzoic acid derivatives increase. The effect of new surfactants on the technological properties of cement slurries was studied. It was shown that, at low concentrations, the retarding effect of surfactants increases linearly with an increase in their concentration and surface activity. In this case, the formation of surfactant adsorption layers leads to a decrease in the hydration of cement particles. It was established that at high concentrations adsorption of surfactant aggregates on the cement surface occurs, which leads to increased stability of the dispersion and a sharp decrease in the setting rate of the cement mass.
