Key Factors Affecting Strength Development of Steel Slag

The mixing ratio of steel slag to dredged soil was set to 37 by volume. As the dredged soils and the resulting mixtures were all saturated with water, the necessary weights of the surface-dried slag particles and saturated clay required for blending were calculated from the properties and the water content reported above. The measured bulk
