Effect of Acetylene Glycol Surfactant in Epoxy Resin Grouting Material
摘要
Abstract
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 S1 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.关键词
