Abstract: Cement-soil technology has been widely used in engineering because of its lower cost,convenience for construction,and good performance.However,in some engineering,the erosion environment has significant effect on the mechanical performance of cemented-soil.Through the mine waste water,domestic sewage,paper mill effluent,three common erosion environment analysis of compressive strength cement-soil test block in different ages.To reveal the compressive strength of cement-soil test block about erosion environment and age,provides the basis for that the similar environment condition can use cement-soil technology.
