%X Two types of modified epoxy resin grouting materials were formulated by incorporating different structured non-ionic surfactant alkynyl glycol into CW slurry. The viscosity, surface tension, contact angle, permeability, and mechanical strength of the cured slurry were investigated. Findings indicate that the addition of surface-active agents has no evident impact on viscosity, compressive strength, or tensile strength of the consolidated slurry. However,surface-active agents enhance the adhesive strength and shear strength, reduces surface tension and contact angle, and improves slurry permeability in clay. Addition of surfactant S<sub>1</sub> significantly enhances adhesive strength, tensile shear strength, and permeability in clay by 23.6%, 37.5%, and 109.4%, respectively. Mechanisms underlying surfactant-induced improvements in slurry permeability are preliminarily discussed based on the tests.
