Abstract
Recently, chemical soil stabilizations are actively adopted for the improvement of the soft ground on which the road and the foundation for offshore structures will be constructed. The industrial by-products such as gypsum, coal ashes, blastfurnace slag and basic oxygen furnace slag can be used effectively for the soil stabilization. In this paper, the characteristics of soil stabilizations with various industrial by-products are discussed from the viewpoints of the types of reaction products which are responsible for the development of strength in the stabilized soils.
