Abstract
In order to apply the mixtures of dredged soils with slag to geotechnical field, the compressive strength characteristics should be identified. In this study, unconfined compressive strength tests for two local dredged soils mixed with three different types of slags were performed. In this study, factors affecting the compressive strength of soil-slag mixture including the types of dredged soil, types of slag, mixing ratio of soil/slag and mixing water content were investigated. Higher slag portion in the soil-slag mixture induces greater strength improvement. The increase of compressive strength in soil-slag mixture was more significant in the case of mixing with steelmaking slag than GFNS and AFNS. The sufficient fine content of dredged soil and CaO of slag was found to have a significant influence on the solidification effect. In addition, the initial mixing water content was higher, strength improvement might be limited.e different types of slags were performed.
