Engineering properties and microstructural features of the soda residue

The soda residue has been utilized as the foundation soil. The specical chemical composition, formative process and micro structure lead to the difference between the macro properties of the soda residue and those of other natural soils. This paper analyzes the engineering properties and the microstructural features of the soda residue, and studies the interaction between the soda residue and the blended material calcium richened fly ash.
