This paper researches a kind of anti?seepage slurry material using organic bentonite, cement and fly ash as main ingredient, which used in landfill anti?seepage engineering with low permeability coefficient and specific mechanical properties. The seepage properties, unconfined compressive strength deformation and stress of the slurry material are analyzed. Experimental results show that the organic bentonite?cement anti?seepage slurry material has obvious superiority than clay?based slurry in the aspect of seepage control with wider application value. The stress?strain curves of organic bentonite?concrete impervious grouting concretion body on unconfined compression test is softened, and it’ s ultimate strain increases significantly which can effectively adapt to the change in foundation soil.
