“…Stabilization mechanisms for traditional stabilizers have been extensively investigated, and rational application guidelines and laboratory testing manuals are available for their effective use in geotechnical engineering practice (e.g., Chew et al, 2004;Cuisinier et al, 2011aCuisinier et al, , 2011bHorpibulsuk et al, 2014Horpibulsuk et al, , 2015Nalbantoglu and Tuncer, 2001;Přikryl et al, 2003;Rahmat and Ismail, 2011;Sukmak et al, 2014;Yong and Ouhadi, 2007;Yunsheng et al, 2010). On the other hand, though various types of non-traditional additives in liquid and powder forms are extensively marketed by a number of companies, little guidance for their effective use in practice is available.…”

Chemical stabilization involves the use of chemical agents for initiating reactions within the soil for modification of its geotechnical properties. Cement and lime stabilization have been the most common stabilization methods adopted for soil treatment. Cement stabilization results in good compressive strengths and is preferred for cohesionless to moderately cohesive soil but loses effectiveness when the soil is highly plastic. Lime stabilization is the most preferred method for plastic clays; however, it proves to be ineffective in sulphate rich clays and performs poorly under extreme conditions. With such drawbacks, lots of researches have been undertaken to address the issues faced with each stabilization method, in particular, the use of solid wastes for soil stabilization. Solid waste reuse has gained high momentum for achieving sustainable waste management in recent times. Research has shown that the use of solid wastes as additives with and replacement for conventional stabilizers has resulted in better results than the performance of either individually. This review provides insight into some of the works done by earlier researchers on lime/cement stabilization with industrial wastes as additives and helps to form a sound platform for further research on industrial wastes as additives to conventional stabilizers.

“…Numerous researchers have worked on the utilization of different solid wastes as pozzolans in soil stabilization. Fly ash (FA) [2,3], rice husk ash [4,5], ground granulated blast furnace slag [6,7], phosphogypsum [8,9], bagasse ash [10,11], waste paper sludge ash [12], press mud [13,14], red mud [15,16] and egg shell ash [15,17] are some of the materials that have been used as pozzolans in lime stabilization of soils. It has been found that using industrial solid wastes as auxiliary additives to cement/ lime stabilization further improves the stabilization process [18].…”

This investigation involved the examination of pozzolanic benefits that resulted from the amendment of lime stabilization of a soil by using a combination of two industrial wastes viz. Fly ash (FA) and Steel Slag (SS). Two lime contents (6% and 8%), which represented the control specimens, were selected for stabilizing the soil, one above the Initial Consumption of Lime (ICL) and the other above the Optimum Lime Content (OLC), respectively. The lime to total solid waste ratio was maintained as 1:1, and the FA/SS ratio varied within the total solid waste content adopted for amending lime stabilization. The unconfined compressive strength (UCS) of the stabilized samples were determined by casting UCS specimens of 38 x 76 mm and cured for 2 hours, 7, 14 and 28 days. After curing, the specimens were strained until failure, to study the pozzolanic benefits of adding FA-SS. The results revealed that the addition of FA and SS improved the pozzolanic strength, ranging from 3.5% to 15%. The optimal dosage of FA and SS also varied with the lime content adopted. For the 6% lime content, a FA/SS ratio of 1:1 was found to be optimal, whereas for the 8% lime content, a FA/SS ratio of 3:1 was found to develop the maximum strength. The amendment of lime stabilization with FA/SS clearly brought about the difference in lime stabilization stages, unseen when only lime was adopted as stabilizer.
