“…Few papers is worth to mention, such as Anderson and Hee (1995), Osinubi and Nwaiwu (2002), Farnezi and Leite (2007), Morandini and Leite (2013) and Amadi and Eberemu (2013). Considering the variation of tropical soil samples already mentioned, it is quite clear the need of more investigation on the topics mentioned before, particularly in the field of hydraulic conductivity and long-term performance of the compacted clay liner (compatibility) that use mixtures of tropical soils and bentonite.…”

Specimens prepared from three lateritic soil samples were subjected to drying under laboratory conditions. Volumetric shrinkage strains were measured at the end of the drying period. Results of this study indicate that, for the lateritic soils tested, volumetric shrinkage strains are influenced by soil composition and compaction conditions. Volumetric shrinkage strain increased with higher compaction water content. The influence of compaction water content on measured volumetric shrinkage strain was more pronounced in specimens with higher fines content. A regression equation was developed from the data to estimate volumetric shrinkage strain given the compaction water content relative to optimum, plasticity index, fines content and compactive effort.

“…Osinubi, et al [10]studied the effect of using Blast Furnace Slag (BFS) to stabilize a lateritic soil to be used as hydraulic barrier. It was observed that inclusion of BFS increased the CBR value to 10% of the soil treated with 9% BFS and it became suitable for the use as hydraulic barrier.…”

This paper presents an experimental study in stabilization of expansive soil using Steel Slag (SS). Experimental program was conducted to evaluate the influence of Steel Slag on improving the engineering properties of expansive clay. A series of tests to measure consistency limits, free swell index, compaction parameters and unconfined compressive strength of natural and stabilized soils. The effectiveness of adding 0, 5, 10, 15, 20, and 30 percentages of SS to the soil was studied. Comparing the results obtained for the natural and stabilized soils revealed that SS has significant effect on strength parameters and considerable improvement in plasticity and swelling properties. Addition of SS to the soil increased the dry density and decreased the optimum moisture content as well as increased the unconfined compressive strength. It is concluded that the use of steel slag to enhance properties of expansive soil is successful and beneficial.
