Effect of Epoxy Emulsion on the Mechanical Properties and Permeability of Cement Mortar

The effects of epoxy emulsion on the mechanical properties and water and chloride permeability of cement mortar and concrete were experimentally studied. The results show that adding epoxy emulsion will improve the flexural and tensile strengths at both early (7 d) and later (28 d) ages, and the 28 d compressive strength of cement mortar, though the compressive strength at 7d will be decreased a little. The suitable dosage of epoxy emulsion is 6~10% (solid content) based on the mass of the cement in mortar. The water and chloride permeability of cement mortar are also remarkable improved when 6~10%epoxy emulsion is added.
