Mechanical Characters of Electric Furnace Steel Slag Mixed Soil

Abstract

In order to explore the resource of electric furnace slag, the mechanical properties and engineering application of electric furnace slag mixed soil are investigated in this paper. First, the mixed soil was prepared by mixing the steel slag and clay mixture in different proportions. Then optimal ratio method for mixed soil is explored with direct shear test. Second, the model parameters of the optimal ratio steel slag mixed soil are determined by the three axial compression tests. Finally, a practical engineering case is selected as numerical simulation object. The optimal ratio of slag mixed soil is used to replace the original subgrade, the deformation of the replaced embankment calculated and compared with that of the original one. The comparison results show that the method proposed in this paper is simple and effective, and can realize the resource utilization of electric furnace slag.
