Soil is the foundation for any civil engineering structures. It is required to bear the loads without failure. In some places, soil may be weak and cannot resist the oncoming loads. In such cases, soil stabilization is needed. Numerous methods are available in the literature for soil stabilization. But sometimes, some of the methods like chemical stabilization; lime stabilization etc. adversely affects the chemical composition of the soil. In this study, Calcium Lignosulfonate and Granite Dust were mixed with clay soil to investigate the relative strength gain in terms of bearing capacity and compaction. The effect of Calcium Lignosulfonate and Granite Dust on the geotechnical characteristics of clay-Calcium Lignosulfonate and clay-Granite Dust mixtures was investigated by conducting Atterberg limits, standard Proctor compaction tests and CBR tests. The tests were performed as per Indian Standard specifications. In this test program, without additives and with additives clay was tested to find the optimum moisture content, Maximum dry density, CBR value, plasticity index.
