In this paper,the compressive strength,splitting tensile strength and flexural strength of epoxy resin modified concrete at 7 d,28 d,60 d,90 d and 120 d of curing age were measured by experiments,the influence of modified materials on the mechanical properties of concrete was analyzed,and the reasonable dosage of epoxy resin emulsion in modified concrete was determined.The test results show that when the epoxy resin content is 15％,the concrete has good compressive strength.When the content is 10％,the concrete has good splitting tensile strength and flexural strength.Adding an appropriate amount of epoxy resin emulsion and prolonging the curing period can improve the mechanical properties of concrete.
