Study on test methods and geotechnical properties of soda residue

Soda residue is different from soils in chemical composition.Therefore,it is necessary to conduct tests on the soda residue in a way different from that of soils.A series of tests were performed on the soda residue,and based on the comparative test results,the basic physical properties were obtained.The mixture of the soda residue with fly ash or clay in different ranges of mixing ratios was also investigated.The mechanical characteristics were studied,and the corresponding results could be used for the comprehensive utilization of the soda residue.
