Utilisation Of Industrial Wastes To Intensify The Engineering Properties Of Low-Flood Plain Soil
Flooding has caused problematic impact to subgrade soil for roads and building infrastructures. The main objective of this study is to investigate the potential of using industrial waste (ceramic dust) in soil stabilisation in view to mitigate the effect of flooding of low-load bearing capacity soil. The achievement of such improvement on engineering properties of the flood susceptible laterite soils through sustainable cementitious technology would nurture the growth of infrastructures development. Extensive laboratory experimental work including flood simulation was carried out to assess the strength and durability of stabilised materials. The fabrication of cylindrical test specimen of 50mm Φ and 100mm in height using locally available marginal laterite soil stabilised with varying mix design composition involving industrial wastes. Laterite soils were stabilised with traditional lime as a control and incorporating industrial wastes ((CD:Lime) at 50:50 and 70:30; (CD:Lime:GGBS) at 10:40:50 and 20:30:50) blending ratios with 10%, 20% and 30% dosages. The results indicate by incorporating industrial waste as blended binder enhanced the engineering properties of the stabilised materials. It is anticipated that this new innovative stabiliser can be used in low-floodplain soil to mitigate the flooding effects.
