The effect of a complex additive based on oxyethylidene diphosphonic acid, soda and water glass on the viscosity and thixotropy of the Stephan Schmidt clay suspension was studied. Using the method of a full factorial experiment, regression equations are obtained that describe the dependences of the structural and mechanical characteristics of the suspension on the composition and amount of the complex additive. Thinner formulations are recommended that provide minimum viscosity and thixotropy values. Tab. 3, bibliography: 4 titles.
