Abstract

In this paper, the mechanical properties and engineering applicationof electric furnace (EAF) slag mixed soil are investigated.The samples of steel slag are taken from a steel manufacturingcompany in Huangshi, a city of China. The mixed soilwas firstly prepared by mixing the steel slag and clay mixturein different proportions. The optimal moisture content for mixingthe soil is investigated from the experiment through directshear test. Based on three axial compression tests, the optimumsteel slag ratio is determined. Finally, the mechanical propertiesof steel slag mixed soil are tested in a practical engineeringproblem through a numerical simulation. The steel slag mixedsoil is used to replace the original soil of the embankment andcompared with that of the original one. The comparison studyshows that the method proposed in this paper is simple andeffective. Moreover, from the practical problem analysis, theoptimal utilization of electric furnace slag can be achieved.
