Ground granulated blast furnace slag (GGBFS) is the by-products from pig iron plants which can cause a serious problem for land, soil, and water. Thus, the study for reusing GGBFS is very nessesary. This paper presents the utilisation of GGBFS for soft soil improvement by cement deep mixing method. Portland cement was replaced by GGBFS from 0 to 100% and a total of 33 specimens were used to determine the unconfined compressive strength and deformation modulus of treated soil. The experimental results showed that replacement of GGBFS from 0 to 60% cement could increase the unconfined compressive strength and deformation modulus of treated soil. The optimum GGBFS content was found to be 30% of cement content. In general, the utilisation of GGBFS for soil improvement could increase the properies of soft soil and soil treated with cement. The result of this study will be basic for utilisation of GGBFS in ground improvement by cement deep mixing method.
