Experimental Study on the compaction behavior of Clayey Soil Stabilized with Fly Ash, GGBS and Eggshell Powder

The present study was carried out to investigate the compaction behaviour of clayey soil through standard proctor test. The compaction characteristics of the soil were evaluated using the standard proctor test. The result showed an improvement in the MDD from 1.607 gm/cc to 1.76gm/cc at 41% mixing material comprising (20%FA+15%GGBS+6%ESP) while the OMC change from 15.80% to 18%. The increase in dry density indicates better packing of soil particles and improves compaction behaviour after treatment                      The experimental result indicate that the optimum mix proportion is 41% comprising 59% clayey soil, 20% fly ash, 15% GGBS & 6% ESP. This combination provides the maximum improvement in strength parameter. Hence, the utilisation of industrial & agricultural waste material such as- Fly ash, GGBS & Eggshell powder promotes an eco-friendly, cost-effective and sustainable approach to soil stabilization..
