In Japan, utilizing the BOF slag (a by-product of steel manufacturing) to stabilize soft soils often confronts problems such as an inconsistency of strength between laboratory result and the field construction. This is due to the different grain-sizes between the sample in the laboratory and the field. This study aims to comprehend the effect of different grain-sizes of BOF slag in the stabilization of soft soils.
