Impact of Lime-Slags Combination on the Hydro-Mechanical Behavior of Clayey Soils

In this study, the effects of two types of by-product materials resulting from the manufacture of iron including GGBS and BOFS on the hydro-mechanical performance of a lime-stabilized clayey soil were investigated. The results indicate that the addition of slag particularly of GGBS has a less impact on the soil engineering properties as compared to lime treatment. It was found that the lime-slag (LAS) combination decreases the water retention potential, controls the soil settlement and causes a considerable increase in the mechanical capacity. The composite clay sample containing LAS exhibits a better performance than that of lime-treated soil particularly at short time of curing.
