In this study,two kinds of polymer emulsion-modified sleeve grouting materials were prepared with vinyl acetate-ethylene copolymerization emulsion(EVA)and acrylate emulsion(PAE),respectively.The effects of polymer emulsion on the fluidity,compressive strength,water absorption,expansion rate,durability,tensile property and microstructure of the sleeve grouting material were investigated and its cost accounting was executed.The results show that polymer emulsion can significantly improve the fluidity,compressive strength,water absorption,sulfate ...
