摘要：The object of research is the geocement dispersion of the heulandite-clinoptilolite composition of the structural formula Na2O×Al2O3×6SiO2×20H2O, modified with an organomineral additive The results of the effect of an organomineral additive on the colloidal-chemical properties of geocement dispersion are presented. Mathematical models that characterize the effect of the concentrations of constituent organomineral additives on changes in its basic physical and colloidal chemical properties are obtained:– conventional viscosity;– density;– wetting angle;– surface tension;– works of adhesion, cohesion and wetting of geocement dispersions,factors X1 ... X3 have an influence that are significant. Also, the joint effect of factors, respectively, x1x2x3, x1x2, x1x2 and x1x3 has a significant effect.The coefficients of wetting and spreading of geocement dispersions are significantly influenced only by the joint action of the factors x1x2x3.Relationship is established between the conditional viscosity and the wetting coefficient, between the wetting angle, adhesion, wetting and spreading work and between the density, surface tension and work of cohesion. The composition of the organomineral additive is optimized and the areas of permissible concentrations of its constituents are determined:– along the X1 axis, 2–2.3% of polymer RI-551Z;– along the X2 axis, 2.1–2.5% of microcalcite;– along the X3 axis, 4.5–6.5% of aluminate cement, which, when introduced into a geocement dispersion, allows Na2O×Al2O3×6SiO2×20H2O to stabilize its colloidal-chemical properties. It is determined that the changes in the values of the other output parameters are tied to the change:– the conditional viscosity and their values are in the following limits: r=1.571–1.766 g/cm3, cosQ=0.50–0.67;– surface tension s=114–128 mN/m;– works of adhesion, wetting and cohesion, respectively, 184–204 mN/m;– coefficients of wetting and spreading -0.77–(-)0.84, -37–(-)55 mN/m.
