Evaluating Groundnut Shell Ash as a Stabilizing Agent for Clayey Sand

Sonam jordan — 2024-06-14

The study explores the use of Groundnut Shell Ash (GSA) as a sustainable stabilizing agent for clayey sand in geotechnical engineering. The research aims to improve soil characteristics by utilizing agricultural waste, specifically groundnut shells, considering environmental and economic aspects. The study analyzed clayey sand through sieve analysis, specific gravity, Atterberg limits, modified Proctor compaction, and California Bearing Ratio (CBR) tests. Results showed that GSA significantly enhanced the dry density and optimum moisture content of the soil, reaching the most favorable stabilization level at a concentration of 8%. However, the study found a decrease in maximum dry density and optimum moisture content beyond a GSA of 8%. The CBR tests showed substantial improvements in both soaked and un-soaked situations, with soaked CBR values increasing from 5.54% to 9.82% and un-soaked values from 6.55% to 10.07%. An additional augmentation to 10% GSA led to a decline in CBR values. The study underscores GSA’s potential as an environmentally friendly agent for stabilizing clayey sand, offering an efficient alternative for soil stabilization and sustainable agricultural waste management.
