Sedimentation-resistant and moderately expanding grouting composition

Abstract

The results of the conducted studies allow us to conclude that an increase in the number of micelles per unit volume of the grouting solution will lead to an increase in its sedimentation stability. The desired effect can be achieved by increasing the concentrations of surfactants in the mixing fluid or by introducing an electrolyte. Since the presence of sites with adsorbed surfactant additive on the surface of the dispersed phase particles significantly changes the conditions for the formation of phase contacts, which, accordingly, will affect the properties of the hardening grouting system.
