Abstract
The admixture Pond Ash and chemical Sodium Lignosulphonate are used for stabilization. The present study is to investigate the properties such as maximum dry density, optimum moisture content and unconfined compressive strength of black cotton soil stabilized with admixture, chemical and combination of both with varying percentages. So, the present study is conducted to check the performance by individual (i.e. parent soil) and combinations of both chemical and Pond Ash with soil. It was expected that, the combination of soil with Pond Ash and Sodium Lignosulphonate may improves Engineering Properties (by means of strength) with respect to parent soil. Black cotton soil is stabilized with the Pond Ash and Sodium Lignosulphonate. The quantities of Pond Ash and Sodium Lignosulphonate contents are varied gradually as 6%, 12%, 18%, 24% and 1%, 2%, 3%, 4% respectively by weight of total mix. Optimum quantity of Pond Ash is determined. Optimum amount of Pond Ash is kept constant and percentage of chemical is varied to study the properties of soil such as Consistency limits, MDD. The MDD and OMC values are determined for IS-light compaction. Maximum dry density (MDD) and optimum moisture content (OMC) were 1.55gm/cc and 24% respectively when BC soil was treated with Sodium lignosulphonate. Chemical alone produced a better results compared to pond ash alone (1.61 gm/cc and 22%) and combination of both (1.58gm/cc and 22%). Unconfined compressive strength value improved by addition of pond ash 1.54(kg/cm2) as (optimum 18% Pond Ash).
