Abstract


The industrialization production rate increases the disposal demand of waste materials. The land disposal method for disposing the waste materials is one of the conventional methods requires a large area of land, but now a days due to lack of land availability these waste materials used as a soil stabilizing agent in soil stabilization technique. Numerous studies advocated the recycling potential of various industrial waste materials such as stone quarry dust; rice husk; coal combustion residuals; furnace slags; foundry, glass, tiles & ceramics waste etc. as a construction material in civil engineering. Due to presence of Montmorillonite as a clay mineral, the expansive soil is a main problematic soil in the history of soil mechanics, which basically causes the alternative swelling-shrinkage in soil at a large extent. This nature of soil reduces the life cycle of structure founded on them. In this paper, the reduction of this problematic nature of soil by blending of stone quarry waste material such as kota stone slurry has been attempted. It is revealed from this experimental study, that these waste materials blended with soil with optimum percentage resulted in a significant improvement in the various properties of problematic expansive soil such as Swelling, Compaction, Strength and Morphological properties etc. Also, it was summarized from study that, the composite material is sustainable and economical viable.
