A Review on Stabilization of Kuttanad Clay with Nano Silica

Soil stabilisation with nano additives is one of the decade most popular trends. The purpose of this study is to see how adding nano-silica to Kuttanad clay affects its geotechnical qualities. Initial properties of kuttanad clay are determined. When different percentages of nano material were added to soil, variations in Atterberg limits, MDD, UCS, and CBR strength properties were investigated. Maximum dry density (MDD) and optimum moisture content (OMC) for Kuttanad clay are to be determined from compaction tests. Uncon fined compressive strength is used to calculate strength parameters for clayey soil. Due to an increase in the plastic limit and a decrease in the liquid limit, increasing the nano silica to soil ratios resulted in a reduction in the plasticity index. As the percentage of Nano silica increases, the quality of the product improves.
